Mtn contract data not loaded

I have a contract with mtn, and as usual they Did debit my account but for the month of october I did not get my monthly data so I decided to call in and find out if there was a default or whatever reason may be. I was given the 1st Mtn *** and was told to wait but nothing happened I then decided to call again I was told there was an error they have to reload it again days later with a new ref number req*** I was told to wait again until when I don't know but my account is being debited without fail but If I was the one with the default my account would have been handed over with just a blink of an eye. Until when must I wait?
