Product: Debt collection

I originally had an agreement with XXXX XXXX XXXX to rent a robot, but I encountered a lack of communication from the company regarding payment concerns. Specifically : I made multiple attempts to clarify discrepancies in my account and request a payment plan, but XXXX XXXX only responded with automated emails and did not address my concerns. 
I was informed that I should have received a {$6000.00} credit through XXXX XXXX ' referral program after referring a hospital that purchased XXXX robots. However, this credit was never applied or confirmed despite my repeated inquiries. 
During the initial demo with XXXX XXXX, I was told that if I missed XXXX months of payments, they would terminate the contract and take back the robot. However, this was not stated in the written contract, and despite my financial difficulties, XXXX XXXX has not taken back the robot or officially terminated the contract. 
After months of attempting to communicate, I finally received a response, but by that time, the situation had escalated unnecessarily. 
Collection Attempt by Davis & Jones , LLC On [ insert date ], I received an email from XXXX XXXX, a XXXX XXXX XXXX at Davis & Jones , LLC, demanding immediate payment. The email states that I must either pay the full amount or set up a payment through their online system. However, the debt collection notice fails to provide proper validation of the debt and does not acknowledge my prior attempts to resolve the issue. 

Despite financial difficulties, I proactively proposed a payment plan of {$180.00} per week, which XXXX XXXX approved to begin on XX/XX/XXXX. I communicated this offer to Davis & Jones , LLC, and provided : XXXX XXXX email confirming the payment plan. 
Records of my previous emails requesting assistance. 
XXXX months of bank statements demonstrating my financial situation. 

Unfair Collection Practices Failure to Validate the Debt Davis & Jones , LLC demanded immediate payment without proper documentation or a clear breakdown of the charges.

Lack of Transparency XXXX XXXX failed to apply a {$6000.00} referral credit and did not respond to my inquiries, making it difficult to resolve the balance in a timely manner. 
Breach of Verbal Agreement During the demo, XXXX XXXX stated that non-payment for XXXX months would result in contract termination and repossession of the robot, yet they have not followed through on this, nor was it written in the contract. 
Pressuring Immediate Payment The collection notice pressured me into making a payment without fully addressing the underlying account issues.

Request for Investigation I request that the CFPB investigate Davis & Jones, LLCs collection practices and ensure that they provide proper validation of the debt. Additionally, XXXX XXXX should be required to clarify : Why my referral credit was never applied. 
Why they failed to respond to my multiple inquiries before escalating the matter. 
Why they are demanding payment while ignoring the verbal agreement made during the demo regarding contract termination and repossession of the robot. 
Whether they properly approved and communicated the payment plan. 
I am willing to resolve this matter amicably but expect fair and lawful debt collection practices. Please advise on the next steps regarding my rights as a consumer in this situation. 

Supporting Documentation I have attached : The collection email from Davis & Jones , LLC. 
My response to Davis & Jones, confirming the approved payment plan.
