Mtn is de*****ing many subscribers. Be aware as you could already be a victim

Mtn is trying to charge me twice. I canceled my contract 3 years ago and settled the balance. Mtn's Legal department and customer service confirmed in writing but now they have some 3rd grade collections agency called Saya recoveries attempting to de***** me by asking me to pay them separately. Please all Mtn subscribers, be very careful of Mtn. Do not assume that they are trustworthy due to their size. It is scary how many people are being de*****ed by Mtn.
