Product: Debt collection

I received a notice from XXXX XXXX located at XXXX XXXX XXXX XXXX XXXX, XXXXXXXX XXXX XXXXXXXX back on XX/XX/year>. I spoke with a XXXX in the accounts payables department as of XX/XX/year> where I received an notice by mail on a past due invoice for XXXX. The original invoice that billed to me a month before on XX/XX/year> was at XXXX with no breakdown over the itemized statement. I spoke with the partial partner/owner XXXX XXXX who XXXX suppose to be over the project with the sub XXXX XXXX XXXX who XXXX the plumber on call that referred XXXX XXXX XXXX XXXX the licensing/contracting for the provided at the time of service. When speaking to XXXX XXXX and XXXX XXXX in the corporate office, I stated that if I started a payment agreement, would there be any collections process I would need to be aware of. XXXX and XXXX both agreed that this would not be turned over to collections while making a payment agreement on the invoice while I was disputing the charges for time and material. The only thing that was on the past due invoice was for the water heater that was agreed upon for the XXXX. I made a good faith payment for the water heater that was agreed wtih for the services verbally since XXXX XXXX doesn't have any self services online to pay on invoice unless the corporate office sends you a link where you either have the options to mail in your monthly payment or have to do a self service every month versus autopay. Unless the agent takes the payment and charges a fee. I then recieved a demand letter with XXXX XXXXXXXX who is controller over XXXX XXXX. The invoice only stated as following " Installed XXXX ( XXXX ) XXXX amp, XXXX volt circuits for tankless water heater per quoted cost of {$XXXX}. All other work was time and material. Ran XXXX circuits from the panel to the bathroom for the whirlpool tub. We also ran a leg for and installed a vent fan. We relocated XXXX switches and plugs. We installed a junction box in the crawl space for some wire joints that werent in a junction box as required. Removed old laundry light and installed new light supplied by owner. Replaced dryer receptacle as directed on new wall. Trimmed out bathroom to complete work '' She sent me an intent to pursue legal action over the account when I made a good faith payment towards the balance within 30 days from the last payment on XX/XX/year>, it was sent by VIA postcard with XX/XX/year> with statements in marker on the outside showing urgency/priority with validation on the services due with " time/materials '' from my first initial request I requested from XXXX XXXX. I then spoke to Rebel XXXX back on XX/XX/year> to discuss explanation on these expectations with her on the past due invoice and expectations on payment options. She informed me that she would work with me on options to resolve where I could set up with the water heater invoice while I was waiting for my dispute on the validation of debt for the other charges/services provided. We agreed verbally by phone to start making a payment starting on XX/XX/year> anmd that I was going to make the payment early for the month of XXXX if I recieved the payment self service. Rebel just deciedd to not honor the agreement and send me a email wanted to demand payment and asked me if there was a service rendered. XXXX  referred my account over to her attorney office within 30 days from my last known payment. I spoke with the XXXX XXXX XXXX XXXXXXXX XXXX, the didn't verify any of my information on XX/XX/year> and jsut started going over the invoices without proper verifications, XXXX XXXX was very deceptive and unfair by stating that she doesn't need to communicate with me on the invoices or itemsized statements from the time of service even though she had the last invoice she assumed I had in front of me. She refused to answer if this was a XXXX party or XXXX XXXX collection agency on behalf of their client XXXX XXXX and violated several FDCPA laws by being unfair asking if I was able to speak several languages on XXXX form of question " Are you able to go over the invoice that was forwarded over to her office? '' She refused to send me over to anyone else to speak to at the XXXX XXXX XXXX XXXX XXXX XXXX and just provided either family XXXX XXXX XXXX XXXX discuss this further and demanded I mail out a hard copy of my dispute over the time of service and validation of debt versus offering email options. I have move details if needed for my dispute and complaint against the XXXXXXXX XXXX XXXX XXXXXXXX XXXX and XXXX XXXX since they are unwilling to help in regards to resolving this matter. I can and will provide the violations of the FDCPA as well in regards to the process/practices of collecting this debt if needed. Also, there was no demographics provided on or a signed contract with the XXXX company providing any details of the validation with estimates/quotes from the submission of the past due invoice. ATTACHED ARE THE EVIDENCE OF THESE ATTEMPTS WITH ORIGINAL CREDITOR AND XXXX XXXX ON ORIGINAL CREDITOR BEHALF.
