TELKOM DOESNT WANT TO PAY ME BACK!

I HAVE RECEIVED THE WORST SERVICE FROM TELKOM. THEY INCORRECTLY BILLED ME TWICE IN DECEMBER. I HAVE CALLED COUNTLESS TIMES TO GET MY REFUND! I WAS TOLD THAT THE REFUND WILL BE DONE IN 10 WORKING DAYS! I LOGGED A CASE ON THE 24TH OF DECEMBER. TODAY IS THE 22 OF JANUARY AND YET I HAVE STILL NOT RECEIVED MY MONEY! <br> I CALL THEM EVERYDAY AND STIL GET TOLD MAYBE BY THE END OF THE DAY!<br> <br> THIS IS THE WORST CUSTOMER SERVICE EVER. TO THINK I HAD COMMITTED TO A 2 YEAR CONTRACT WITH THEM IS RIDICULOUS!
