I WENT TO THE STORE IN THE PICK N PAY CENTRE IN CAPE TOWN , MYNETTE WAS THE PERSON HELPING WITH THE UOGRADE . I ASKED HER TO CAPP THE ALL LINES ON MY CONTRACT , HER REPLY WAS THAT SHE IS OFF-LINE BUT WILL DO IT LATER , THIS WAS NEVER DONE , WITH THE RESULT THAT I RECEIVED A BILL OG R952.00 FOR DATA USAGE , BECAUSE THE LINE WAS STILL UNCAPPED , THE BILL JUST INCREASED , SHE B=NEVER TOOK THE TIME TO EXPLAIN WHAT MYCHOICE MEAN OR THAT YOU CVAN CAPP THE PHONE FROM YOUR DEVISE , THIS WAS ONLY EXPLAINED WHEN I CALLED THE CALL CENTRE TO QUERY MY BILL , I HAVE LOGGED A COMPLAIN WITH MTN A WEEK AGO BUT TODATE NO FEEDBACK .I FEEL THAT IF THEY HAD DONE THE JOB AND EXPLAINED THE TERM OF MYCHOICE , I WOULD NOTHAVE HAD THIS BILL IF THIS WAS EXPLAINED AS I HAVE PREVIOUSLY BEEN ON A TOPUP CONTRACT ,AND THE INSTRCTION TO CAPP THE PHONE WAS ADHERED TO . I FEEL THIS LADY FAIL TO DO HER JOB AND I AM LEFT TO PAY FOR HER INCOMPETENCE . SHE DID NOT EVEN OFFER AN APOLOGY <br> THE PHONE ALSO SEIZED AND TODATE HAVE NOT BEEN REPLACED
