Midland Credit Management, Inc. MCM Sent me a bill for $807.39 naming T-Mobile as Original Creditor - this is false! San Diego, California

I received a collection letter from Midland Credit Mgmt. Inc.  Channel 4 (WSMV) of Nashville reported this as a scam on people including the News Anchor of the station.  They claim this is occurring against elderly people for the most part.  I am 73 years old.

Midland Credit Mgmt. (MCM) is making attempts to collect a bill from me for $807.39 they claim to be for the Original Creditor T-Mobile account No. 372540555.  The collection letter is from H. Torres, Division Manager for MCM.

I have not had an account with T-Mobile ever, ever.  The letter from MCM assigned an MCM account number to me of 8553088840.  From the letter:

"Your past due balance of $807.39 with T-Mobile is being reported to credit reporting bureaus and remains a negative item on your credit report."

This appears that they are try to scare me into paying a bill that I never created or responsible for.
