MTN - Upgrade, no service, no data, no feedback BUT charged for all

I have upgraded two of my lines to the following packages on line:

Application reference: *** for number: *** Application reference: *** for number: ***

I have received both the contracts via email on: ***

Yet, I have not receive the data. I logged several calls with absolutely no luck! And of course I am being billed for the new amounts.

I need this cancelled or resolved ASAP please
