Pricing and migration

I have been with the network for 11 years. I recently renewed my contract online and took a smart 100 package.<br> I usually buy a gig of data and more when needed. I have been seeing some funnies but only started monitoring last month. I did not go out of bundle last month, yet I received a data bill of 75 rand. How does that work? How many other customers are you guys over charging? So in order to monitor my account properly, I wanted to migrate to a uflexi 200 (since the price of a smart 100 and uflexli 200 is the same). I was told that I could only migrate after 3 months? No one mentioned that to me previously. Secondly the account was upgraded on the 25/02/16, only received the device after. Now I can't even cancel the contract? So you can continue to rob individuals of their hard earned cash? I have previously logged a request and had reference numbers but no one calls back. I know yesterdays reference still has 24 hours but I am not holding my breathe. The problem with you mobile providers is you think you have carte blanche on your operations. It is a rather pathetic attitude. If a customer is unhappy with a contract since there are anomalies they should be able to change.
