Useless Call Centre!

On the 26th of November I saw the 2GB top-up special for black November and decided to upgrade to that as my current contract was over . This was done successfully through the call center. I was told the benefits for the new contract would kick in from the next day. Not surprisingly, nothing happened so I phoned the call center again and the agent told me that the benefits would only start from the 1st of December. Again, the first of December arrived and nothing happened. The next agent at the call center said it was because it takes a month's notice and by the 1st of January the contract would finally be active. By now I knew that they were talking ******* but I still waited eagerly for the 1st to see what would happen. Nothing again! I then spent a full hour on the phone being transferred from retentions to upgrades and then to the regular call center and was finally told my upgrade was cancelled. I guess the only option now is to move to prepaid. Not sure how Cell C stays in business with call center agents like this. I guess miracles do happen. To be honest, the in-store agents are usually very good.
