GC Services was mistakenly given a telephone bill from ATT which we had paid at termination of services. We contacted ATT and GC about the matter and were assured it was resolved. They even wrote us a letter about it. We thought the problem had been resolved until now almost 10 years later we find the bill still shows in our credit report. I can't believe the incompetency of this company. I don't know what to do about it because now they won't answer my calls, they don't correct their mistake. I would pay it again if they would actually do something, but I believe that they care not about their reputation. Collections agencies serve a good purpose, but this moves GC Service from Good to Very Poor. I just can't believe their lack of good faith.
