I am writing this letter because I have repeatedly requested a BREAK DOWN of this past due billing information that I have received. 

I have repeatedly told MCM that I do not owe this amount because I was on a monthly plan with XXXX paying {$50.00} a month. The bill that they are charging me for looks to be adding the cost of a Galaxy S phone hat I was using my sim card in, but that phone was on my husband account and not mine. He was charged for that phone and paid it off on another collection account with MCM. They are trying to charge us XXXX for the XXXX phone. I was using the phone ( switch my sim card ) but my husband was the one who had got the phone on another phone number and not mine. I am inclosing a copy of the billing information I have received, and as you will see they still did not break down the past due billing for me, only telling me I owe X amount for this account. 

I am asking to have this account dismissed and removed from my records because I am not paying for something I have tried to explain to them I do not owe.
