Product: Debt collection

I am disputing a debt collection from a XXXX billing. The service that I sought to receive from XXXX is not available in the area in which I live. I asked XXXX to disconnect this service. XXXX appears to have misidentified my reason for the disconnection request. I have tried to resolve this issue of miscommunication with XXXX with no success. I have engaged assistance from the New Mexico Office of the Attorney General and have filed a consumer complaint with that agency. I disagree with XXXX that this is a valid debt. 
In XXXX, XXXX, I got a residential 12 month internet service contract with XXXX. 
In XXXX, XXXX, I got a business account with XXXX. I spoke with XXXX on XXXX/XXXX/XXXX, and he offered high speed internet and phone for {$99.00} and a startup fee of {$84.00}. There was no mention of a contract. There was no mention of early disconnection fee. 
In XXXX XXXX I realized there was massive mold in my rental, got sick, and had to move out quickly. I moved to XXXX, NM XXXX XXXX, XXXX. 
When I realized XXXX did not service XXXX, ( new landlord told me ), I just thought I could drop off the equipment to the XXXX office in XXXX XXXX, and disconnect services. The XXXX agent asked if I called to cancel. I told her I thought we could do that now. No, the XXXX agent instructed me to call. It was then that I was told I had an early disconnect fee " of about {$2000.00}. '' So, I have been having multiple phone calls with XXXX since. There are several things XXXX did in the next 2 weeks that are fishy to me. I kept getting email reminders to " activate the account. '' I opened the email to investigate, and it said I could not activate this account, so I spoke with XXXX employee XXXX on XXXX/XXXX/XXXX, she said I could not get a business account, and never should have gotten one due to I still owed {$100.00} on the previous residential XXXX account. I was having some financial challenges at that point, and qualified for being eligible financially for Medicaid. So, I never actually ever activated the account. XXXX XXXX, XXXX I received a bill to the residential account. Then in XXXX XXXX it was back to the business account. In one of my phone conversations with XXXX I learned the residential account was just disconnected XXXX XXXX, XXXX. 
I have been talking to them almost daily to attempt to resolve this. 
I do not recall agreeing to the 36 month contract, so I asked them where did I agree? XXXX emailed me a contract, with 36 months term, and my digital signature. ( XXXX Contract attached ) I had never seen this document. They said I agreed over the phone, and I asked them to send me the recorded call where I stated agreement to 36 month contract and early disconnect fee, they said they ca n't find it. 
On XXXX/XXXX/XXXX I asked to speak with a manager, they said a manager would call me within 72 hours, and I have not heard from a manager yet, today is XXXX/XXXX/XXXX. 
In one conversation with XXXX, the agent XXXX said to send a copy of the lease for the new residence in XXXX, because XXXX does not service XXXX. XXXX then said they could not accept the new lease due to it being handwritten. They said they would accept a utility bill yet all utilities are included in the new rental, so I do not have a utility bill. They refused receipt from post office box rental. I was going to discuss with the XXXX manager getting the lease notarized, yet I never heard from any manager. 
As of XXXX/XXXX/XXXX the last statement from XXXX is " we are sending you a bill for early disconnect. " As of today I have not been able to resolve the dispute. I have been highly disturbed by this ongoing stress due to the amount of time I am spending on my attempts to resolve this dispute and the anxiety waking me up at might. 
On XXXX/XXXX/XXXX I returned a call to XXXX XXXX, a collection ag
