Very bad service

The call center staff do not even try to help,they don't make an effort at all. I paid my debt and 7 working days later they haven't removed it from the bureau instead they listed me for an amount which was supposedly a discount from them and I am sitting here with a paid up letter that serves no purpose at all because i still owe them according to the bureau. Why did they give me a discount when they didn't have the intent to remove my name,why did they give me the paid up letter if I still owe them? This company is ruining my life. I sent numerous emails,I have called them and no one seems to know what's happening? Is this a joke ? If that's the case then it's not funny at all
