No feedback from MTN Clearwater mall

On the 30.12.2017 I went to an MTN store at Clearwater mall to purchase WIFI for my house. I have been an MTN client for over 10yrs and still am. So since I have an active contract with them I was informed I just need to add an extra line to the existing account. The consultant at the store was very helpful and answered all my questions even gave me useful advise. Great service from him honstely. We did the necessary paperwork and he submitted everything to what he called the vetting department. He then informed me that he will call me as soon as all has been approved. It is now the 10th Jan 2017 and no feedback has been received. Two days ago I took to twitter to complain and tagged @mtnsa which send my tweet to @mtnservices to assist. Till now no response or even an sms or acknowledgement of my tweet. The consultant did mention that they always have issues with vetting or whatever it’s called department. MTN clearly my business is not important to you, 10yrs of loyalty means absolutely nothing to you. This is really disgusting and totally unacceptable. Your poor customer service keeps going from bad to worse and you have zero respect for me as a paying customer.
