I 'm in a dispute of charges with XXXX XXXX, over a pro-rate charge vs. a full month charge. XX/XX/XXXX a ended my services with XXXX, paid the last month bill ( exhibit A ) and was told that a final bill will arrive in regards to the period between the last billing and the discontinuation of the service from XX/XX/XXXX-XX/XX/XXXX. 

I received the bill but it was a full charge of {$92.00} ( exhibit B ). 
I called XXXX, told that my contract was long expired and that I should be paying only the pro-rate charge. Level XXXX customer service rep. said she could not do anything for me and all the " Executive Customer Service Reps '' were busy, then she took my callback info and said that such rep would contact me in 5 business days. This never happened and instead I received a letter from a collection agency. 

I responded to the letter in writing challenging the charges and demanding them a verification of my debt, they did n't replied to me. 

On XX/XX/XXXX, I received a letter from another collection agency called West Asset Management ( WAM ) about the same charges. On XXXX XXXX I sent them the same letter I 've sent to the previous agency asking again for proof of debt. ( exhibit C ) .This is a standard letter to debt collector asking for proof of debit and requiring them under the Fair Debt Collection Practices Act to do not notify any credit agency until the debt is confirmed in writing, etc ... 

To my surprise, they informed XXXX and XXXX about this collection on XXXX XXXX, and of course my credit score dropped about XXXX points since ( exhibit D ). 

The letter for verification of the debt only came from West Asset Management on XXXX XXXX where they only included the last bill from XXXX, which I 'm aware of, and it is exactly what I 'm disputing here.
