Incorrect information provided - higher cost

My Wife upgraded her phone contract at the end of January 2015. I went with her to the shop. I asked the consultant several times about out of bundle call rates and was assured that the out of bundle rate for a Mychoice 100 is R0.99 per minute.<br> The contract was signed and we received the new instrument. In March, we are still billed at the previous higher rate, and the branch does not even have a copy of the contract.<br> When I phone MTN (808) I am told that there is a penalty for taking a lower contract and that call rates are R1-60 per minute.<br> How can the branch and the help line provide such differing information? If the branch told me that the call rate was R1-60 I would not have taken out the contract!<br> I am trying to get the real information but am referred back to the branch with consultants who cannot answer the questions!
