Vodacom unhelpful and unable to resolve a simple issue

I have been on a UChoose Flexi 200 contract for over two years. I have always been able to use the R200 for calls, SMS's or data, whatever I needed it for. At the beginning of June I was no longer able to use this for data at all. After calling the call centre, the agent, Jacques, did a few checks, I was advised to take the phone and sim to a branch in Tygervalley Centre, Cape Town. I did so, but the man (Lyle) who attended to me, was very unhelpful. He hardly looked at the phone and said I must phone the call centre back to activate out of bundle rates. When Jacques from the call centre called back to hear if the issue was resolved, my husband told him what Lyle said. He confirmed that his was not the problem. Then we escalated it, on Jacques advice, via e-mail to ***, who hasn't answered any of our emails to this day. So, now we are stuck, left with the only option of leaving a bad review on Hellopeter.
