Mtn Settement letter

Mtn has the worst customer service ever!!! I have been calling Mtn Customer service for a settlement letter or to tell me where my account is, and was sent to 7 people within 20 minutes on a Friday. On Monday I phoned Customer service again, and got the sent around again with the promise of a Supervisor that was going to phone me, but still that also did not happen even on the Friday I was told they could not log into my profile as it was a Legacy Account. Was sent to my nearest MTN store, but also there I was being told that Legal was supposed to help me, being also not true. Up and till today after emails and all my airtime, I am still not being helped at all!!!!
