Poor resolving

I am totally disappointed with Vodacom whom I have been with for more than 15 years. Last year around May my data contract was up for an upgrade. At the time I had multiple sims connected to this data contract. So I upgraded and got a mini iPad in the process. Unfortunately this device could not connect to the Internet. Apparently to many sims linked to one data contract. Anyway gave it back and asked for my contract to be status quo. This was at Broadacres...Took 3 months to resolve. Anyway tried to get this done in Cape Town a few months later. Got the IPad and was told it will work. Was upgraded to a top up scheme...which was not fully explained to me. So once the contract kicked in on the 1st of the month all my devices could not pick up service...which was late last year. the call centre agent, last month, said the reason is because I was not on an open contract as I was before. So did the deed and now it's March..almost a year now. I have not been able to use the data on my contract and am paying for it still too. Was just at a branch in fourways and was told I need to visit the branch in Cpt to resolve. Imagine that...Disgusted. Want to cancel, but told I will incur penalty.
