MTN has a very poor customer service

My account was in arrears and they suspended my services but they were still charging for normal data prices as if i was using it .i managed to settle the account but now they’re are telling me that it is going to take more than a week for my services to resume. I asked them what is the problem now because i have settled all the money and i told them that ,when i paid at the store they said my services were going to resume immediately but now they are telling a different story. Please assist me i need my number as soon as possible.
