SERVICE NON EXISTENT

Been with Vodacom nearly 25 years. All of a sudden the debit order does not go through at financial institution. Recieve SMS, phone the accounts dept at vodacom. They say doesn't make sense , order is active , they will rectify problem. Then BOOM I get disconnected , I HAVE TO GO TO A VODASHOP TO PAY ARREARS, FIRST SHOP NOT ON LINE , FIGURES, 2 SHOP THANKFULLY ON LINE. THIS INSTITUTION JUST GOES FROM BAD TO WORSE. IF YOU CANCEL AN OLD PHONE , OR CONTRACT IT JUST IS NOT DONE , YOU CANT CANCEL AT A SHOP , HAVE TO DO IT VIA PHONE , NEVER GET YOUR REF NUMBER ETC.
