Upgrade misery

I upgraded about two weeks ago. It was uncapped and u get a simcard with 1GB...It was activated but have never loaded my 1 GB. The Glen Telkom said they will activate it but to date it hasnt been activated and one cannot get hold of them cause they dont receive calls . I then got to the call centre on ********** 342 and spoke to Mark and have been struggling to date with this query....I have told them that they can collect the wifi route, remove my landline and cancel everything including my contract by yesterday if not sorted out and today when I tried to contect Mark he is not in. Am I a fool to be phoning Telkom for 2 weeks. Pathetic service
