I got a collection notice in the mail yesterday from (whatever) collection agency. They were trying to collect $750 for TMobile. I haven't been with TMobile in over 10 years. But now, all of sudden I owe them money. In the fine print, it says that this debt is so old that TMobile will not sue me for the balance. Then it says said collection agency can neither sue for debt nor report it to credit report. So if I owe a debt, shouldn't they be able to make a negative report on my credit? It sounds more like a scam to me. Do they just find old closed accounts and try to collect money on them? What's next?
