MTN still taking my money after 10 months for a "FREE" tablet = What a joke.

I have logged a review on 16 June 2018. See below is the complaint. And still no feedback. I don't want to even give them 1 star. Where can I report MTN?? 10 Months of calls and emails and MTN don't care about the customers. Still paying for a "FREE" tablet. At this moment they are *****ing my money because they are aware of the problem but decides to do nothing about it. I phone and emailed the branch again almost every week and even they don't care. I will NEVER upgrade with MTN again. ---------"Struggling to get any feedback from the Local MTN and Head office. Every time they promise to give feedback within 24 to 48 hours but after 8 months still no feedback. When I upgrade in November 2017 to the P10 there was a special where you get a tablet and data for free with the P10. Since then I am charged R150 each month. First I phone Janovia Skieman at MTN College square in Bloemfontein and day after day she promised me that she will phone me back or send feedback. In May I decided to try the call centre as Janovia NEVER phoned me back as promised and call centre logged a call (1- ********** 1736) Spoke to Jayshree on 14/05. She said I will get a sms within 72 hrs. On 23/05 I phoned the call centre again and spoke to Jabulo. He said that he escalated this to his manager. On 28/05 I phoned again and spoke to Nkosi. She also escalated this and said i will get feedback within 24 hrs. On 7/06 I phoned again and spoke to Thakanie. Again this was escalated to a manager. On 14/06 I phoned the call centre again. Explained my whole story and gave all the call reference numbers and was holding the line for almost 15 min and was cut off. Then I tried the Local MTN at college square and asked to speak to the manager. The lady said that the manager was busy but will phone me back. 3 Days later still no phone from the manager as promised again. Everyone is making promises and STILL NOTHING. I am paying R150 for 8 months now for something that was supposed to be "FREE". I am really fed up. MTN is taking my money and time."
