Poor Service

I have one compact decoder which is R399 per month and multichoice has been billing me R798 every month. My services was getting cut off when I did not pay R798 each month. I have made several enquiries each time I was promised that i will be called back to process my refund. The last call I made was on 24 March 2020 and the consultant assured me that they will phone me back within 48 hours to process my refund. To date I have not heard anything from multichoice.
