Vodacom online and service

Vodacom online / rewards department. You messed up my order and **** about the amount and the order was cancelled and now still 7 days later it still show it is a future open problem. I have been phoning non stop to try and resolve the issue but no-one seems to know how to remove it from my name. Each one blaming the next person and the Managers keep saying we will resolve it and it is escalated and and and... Managers will phone back but they dont phone back. How long can this take... it has been 7 days and you cant resolve a small problem on your side .... pathetic service, never ever do bussiness with them online.
