Shafted by MTN

I have had the most awful experience which is still going on. I have a mobile device that has not worked in 2 months, the open docket after docket with no resolute. I have fixed wifi lte device 3 data bundles and 3 mobile devices with them and they still continue to leave me in the lurch. I want this fixed now. I CANNOT MAKE OUTGOING CALLS. The next step will be legal action. The in store service has been incredible, the Port Alfred branch has been nothing but helpful. But corporate do not give a continental whether their customers are happy or not. And more so to no have the due diligence to follow things up. Sickening!
