BAD BAD BAD Service

I am so disappointed with MNT's service!!!! When we switched from Nashua to MTN it was all just down road from there!!! I do not receive any statements on my account, I signed contract for a lesser amount and then they charge me more than I should pay and it is on Top-up, when I try to call MTN regarding this matter for about 5 months now nobody can assist me in the matter!!!! I took countless times off from work to resolve this matter at a MTN store but it is so unprofessional, you have to wait for more than a hour just to be helped!! The staff even have to call from a cellphone exactly the same number that you could call by yourself which all still just result in no answer!!!!! This is unacceptable!! Now my account has been handed over because of no payment, but how do you expect me to pay when I do not even get a monthly statement, when I get over charged and I do not get any help regarding this what so ever!!!!!! I seriously will never ever recommend anybody to use MTN!!!!
