Account debited after cancelation/bad service

I called RMCS on 03/03/2015 to cancel my airtime contract with them and request my PUK number for my cellphone. I had to call the again on the 28th April after none of my request were done. I spoke to Tshidi on the 28th a great lady who explained that the last person did not do his job as per ref no : *** of ***5. she then said tomorrow my requests should be resolved, which was suppose to be ***5. ref no : *** and ***. None of this was done. i called this morning spoke to Neo ref no ***, who said i should call after 3 hour for the PUK, fortunately i got the PUK after throwing tantrums, but still my cancelation is not done and the amount on the statement is still not reversed for March and april 2015. RMCS has pathetic service, i have never been given such horrible service as them. is like they are running a ****a shop. Their admin Department clearly is not effective as everything is reffered to them but nothing is done and their 24hours turn around is not adhered to. i blame the 1st consultant i spoke to for not doing his job, the rest did well. Is just the company process itself that mediocre. please cancel as per request.
