Midland Credit Managment, Inc. Trying to collect a debt, they bought from T-mobile that I do no owe. San Diego California

Midland Credit Management contacted me in 2012, for a debt they said I owed to T-mobile in 2012, meanwhile they put a negative on my credit, I told them I didn't owe T-mobile or them anything. I got a package phone deal from T-mobile for my business in Inglewood, Califorina, which, would inable for me to advertise over the Internet, but, it never worked, I complained to T-mobile, they said to try it for 30 more days and it if didn't work, no charge, just return the package, it didn't work and I returned the package within the 30 day period.

I didn't hear from T-mobile after I talked to them and told them I returned the equipment within the 30 day period. Evidently they (T-Mobile) disagreed and sold the bogus debt to Midland Credit Mangement? If, I owed it, I would pay it, they have offered to settle the bogus debt for approximately 2/3rds ($239.63)of what they claim I owe ($399.39) them, but, I do not owe it and I will not pay it! I have just filed a complaint with the FTC TODAY! I was going to start a class action lawsuit against them (Midland and T-Mobile), but, I see a class action lawsuit against Midland Credit managment was just settled for over 5 million dollars, but, I am game to do it again, ASAP! I am waiting for a lawyer to call me now. Midland Credit Managment have harassed me day and night, phone calls and letters, THEY HAVE AFFECTED MY HEALTH and stopped me from obtaining credit to buy a house, or, get a loan for a house. I have asked them to stop numerous times, I am 100% fed up now and amd going after them in every and any legal way I can. I will not pay something I do not owe, it is the only ding on my credit report, but, not for long I hope and pray.
