Extremely poor service

We ( myself and wife) upgraded to the advertised special from MTN in store. We paid the required connection fee and support the same store with all required accessories for the new phones (Apple Iphone 6) Since the day of activation 25 November 2015 we did not receive any data or sms bundles as per prescribed contract although the prescribed monthly bills were fully deducted as per debit order. The case was even reported via the MTN Customer Support Centre without any luck. According to the Branch Support the case is under investigation. I would hereby advise to rather support another MTN Supplier Branch (even perhaps another Service Provider) for better service.
