Worst Experience ever

MTN has been a Nightmare this past few months.

I Took an additional contract on the 7th of April and was bill incorrectly I have queried the issue and tot date I have not been assisted now my line are suspended, all these 3 lines are primary lines for my Brother myself and Mother and for the past days we can not communicate at all yesterday I called MTN and held for over 3 hours and the line disconnected I tried calling again after hours and now am told my account is with legal and they can not help. I requested this additional line to be cancelled but they want to over charge me for something they can not fix
