Unprofessional service from MBD

I have been trying to get my MTN account reactivated for about 6 weeks now. MBD gave me an amount to pay (that they received from MTN) which would get it reactivated. I paid the amount they gave me and then after about another week of trying to get a response from them they gave me another amount to pay (before they could reactivate).. once that was paid it took countless calls and emails for over 2 weeks only to be told that there was yet another amount to be paid. I paid again... and now for the past week I have sent about 3 emails a day to get a respose from MBD and MTN and no replies to my emails and the line is still not activated. This has to be the worst service in the history of service!!!!!!!!!
