Two debit orders with no device delivery

I have app**** for a phone in November 2017. It was approved and my bank account has been debited twice. I have not received the the device up to now.

I have contacted the customer service department so many times. Spending lots of money on phone calls. Every time they tell me they will call me back and that the problem has been escalated to the department responsible.

I have been to telkom stores and they can not assist me because for some reason telkom online is not connected to the stores. This is totally ridiculous.

Where does one go for any assistance that does not cost a fortune in phone calls???
