Unsatisfied customer

I am Melokuhle Dlomo, ID no ***. I bought a Month 2 Month MTN home router for R249 and it arrived on the 06/11/2024. The router connected for a couple of hours then it did not provide internet. I took the router to Amajuba Mall for further enquiries. The technician tried configuring the router but it still did not provide internet access. My colleagues advised me to take my case to Newcastle Mall. I had asked the consultant to cancel my package as I have been calling mtn but they never got back to my calls. He asked me to bring the router so they can send it back to Mtn. This process was done on the 22nd of January with IRMS ***. I kept on calling mtn to cancel but the consultants would take me from one department to the other until one consultant drops my call. I went back to Newcastle Mall and they called the service provider and we got the same results. Mtn still debits my account till date. Can someone please assist and am really not happy with this kind of service, and want all my money which has been debited from my account with from last year. My cell number is *** can someone please call me.
