Useless!

I was a customer of Altech up until May after which I requested my contract to be discontinued. I contacted the company via the enquiries section of their Web page, and my case was persistently closed, after having had no resolution. The contact number was hardly answered. In any event, after EVENTUALLY getting hold of accounts, and after many fights (where I had to send all prior communication to a manager), I was told it would be done. This morning, however, I received a message informing me I have been handed over for an amount which I should not even have to pay. I have had no further communication up to this point informing me that I was in arrears, nor that my debit has not been going through. I was informed that there are NO NOTES on my account discussing any prior communication, or any record of me having cancelled the account. I am now sitting in a position of possibly being blacklisted due to the idiots that work there, and being told to forward THE SAME COMMUNICATION AGAIN. Am I the only one who seems to be missing the point?
