Absolutely Disappointing

I am currently in a nightmare situation. I was called on March 1st with a data deal for R99 as I had just taken out a phone contract with them. I requested to keep my phone number but this wasn't done and I figured that out when I got the message from the couriers, after many calls I was told to sent it back which I did and call back in to redo it. I called today one agent was going to call me back that never happened another agent said the original person needs to cancel and call me back. I say all this to say nobody takes responsibility or is of any help. Agents are passing the buck and at no point keeping their word. If this was done right in the first place it wouldn't be an issue. I have been a vodacom customer for so many years and this is extremely disappointing
