Product: Debt collection

I had home internet with XXXX. I cancelled my service on XX/XX/year>. They billed me for the entire month. I had a chat with a XXXX rep who agreed that since service was ended on the XXXX my bill should be prorated. He initially told me to pay the entire month and then request a refund for the second half of the month of service that was disconnected. I was not willing to pay for service that they did not provide. I had my service disconnected on XX/XX/XXXX and I was willing to pay for the service I received from XXXX XXXX. The rep finally provided a prorated amount. I paid that amount with an electronic payment from my bank on the same day as that chat. I received bills in the amount of {$25.00} for XXXX additional months. I refused to pay for service that I did not receive as a result of my request to end service with XXXX. 
I have now received an email from a collection agency. I attempted to access my cancelled XXXX account following receipt of that email. My username and password were not recognized. I initiated another chat with XXXX. The rep could not find my account. I copied and pasted that conversation below. They erased any evidence of my account and then had the audacity to send a bill to collections. XXXX has made every interaction with them since I started my service incredibly difficult with phone service that would disconnect after being on hold for XXXX minutes, representatives at brick and mortar shops who told me they don't have phones in their stores and that they were unable to assist with internet service, they created unbelievable obstacles for me to return my equipment. That chat is included as well. 

To sum up, I do not owe XXXX any money. They have sent a bill to collections for money that I do not owe. They have made it impossible for me to access my account to review payment history.
