This collection agency is trying to collect a debt for XXXX and XX/XX/XXXX, I contacted them to see why I never received a final bill nor did I receive anything from the collection agency prior to reporting the account to my credit report.  The original customer service agent stated they mailed me all of this and gave me dates and the address it was mailed to but those statements are 100% false because I was living at the address during the time frame she stated the letters where mailed.  I got extremely frustrated and upset when she told me that I need to just pay the debt I owe and pay my bills and then this stuff wouldn't happen.  I ended up hanging up the phone and calling back to get a different representative who then stated that the letters where mailed to me but they were returned to sender as undeliverable.  It's my understanding that if the mail is returned to sender then they can't just take it upon themselves to report it knowing that I was never appropriately notified nor given the opportunity to rectify the account.  I then spoke to a manager that AGREED the debt shouldn't be on my credit and because it was already so late in the afternoon and they where closing, she gave me her name and told me to call  back the next day and she would take care of it. When I called back the next day, it was an act of congress to get the same supervisor on the phone an dwhen I spoke to her she acted as if she had no clue what I was talking about.   XXXX I reminded her of our XXXX hour conversation, she then stated she was going to get with her manager about the rude comments fromt eh original customer representative and she was also going to get with him about removing he account and starting over to follow the laws put into place to prevent things like this from happening.  On top of all of this I requested  validation that the debt was even mine because the rediculous amount of XXXX is what was claimed that was owed and my bill never exceeded XXXX a month.  Obviously if you don't pay, they disconnect your electricity, they don't let you go XXXX months without paying.  Once the supervisor got her supervisor on the phone, she then denied ever telling me anything that she did and said her manager said their was nothing that could be done and even though the mail was returned they weren't deleting it and I just needed to pay it.  Their are laws for a reason but when they aren't required to follow them what is the point in even having them.
