Complaint Review: Comcast - Comcast Cable

In the beginning of this year (2009), we were enticed into changing over our internet and television service from Direct TV to Comcast Cable.  The service was spotty and unreliable from the beginning, but we were determined to make it work because of the promotional rates.  On or about the end of June, we stopped receiving the paper invoice, but we didn't realize it until the service automatically suspended for lack of payment.  In the beginning of August, I had to call Comcast to restore the service and I specifically requested that they send a paper invoice. At that time, the Comcast customer service representative confirmed that we requested a paper bill and also confirmed the correct mailing address.  However, at the end of August (8/28/09), they disconnect the service again because we were again late.  Still we haven't received any paper and I had to call again to restore the service.  Yesterday (9/24/09), I finally received a paper bill that had an additional $16.99 added to the amount owed; Late Fee $7.00, Convenience Fee $4.00, Reactivation Fee $5.99.  Since I haven't see the paper bills from June to September, it is possible that I have been charged these unfair and unethical fees all along.  Today, I asked to speak to a customer service representative who, after 30 minutes of explaining and arguing, she only was allowed to remove the late fee.  She and her supervisor said that the other fees can not be waived.  My question to you, my fellow consumers, is this fair and just.  Should I have been charged fees for something that wasn't our fault in the first place?  How many consumers are charged these fees without their knowledge and pay it without question?  If Comcast admitted to waive the late fee as they just did, they should also remove the convenience fee and reactivation fee.  If I received the invoice, it would have been paid on time with all of my other monthly statements.  I think that Camcast should be investigated and prosecuted for unfair billing practices.
