Paying a lot of money for no service.

I am paying for a freeme family Unlimited plan which cost me R1500 per month. Speed was fine last year and 100gb of Data allocated every month. Since the beginning of January this year I had no service. I had been to Stellenbosch and Tygervalley shop who told me a different story and send me away without helping me. A call was logged with backoffice on the 4th but till today nothing is done. Telkom acknowledge there is a problem but they simply don't bother to fix it.
