MTN'S BAD BUSINESS PRACTISE.

I took up a wifi package last year in October (2018) at MTN in Golden acre in Capetown and not happy with the service or experience. I have been paying R369 for the wifi and it has not been working for almost a year . I have been paying for a service that I am not receiving or benefiting from. I have booked in the sim card and router on many occasions for an exchange and for them to sort out the matter but until now nothing has been resolved, but they still deduct money from my account every month . I have lodged so many complaints since last year to the store manager, sales people, and mtn but still no way forward. I have paid R4428 for a year for a service Im not getting, plus spent so much money buying data as i dont have wifi in the house. I have asked them to give me back my credit and to cancel this wifi contract and to this point I am still waiting for them to resolve this problem. I was very angry this morning as they again even after lodging so many complaints plus escalating the complaints, they still deducted money from my account. The store manager plus sales people there are not efficient at all. They do not communicate with me at all and I must constantly call and remind them of my issue. This is unfair and and violating my consumer rights. I cannot pay for a service Im not receiving . MTN cannot **** me its unfair and this is unfair business practice and *******.
