Disappointed with Contract Sales Agent

After many years as an MTN prepaid customer I decided to upgrade to a contract line. I submitted my application online and received a call from one of the sales agent. I specifically asked him it is possible for me to keep my current prepared number on the contract line and he advised me that I can do this once I have received the new sim card. This all turned out to be a misstatement because the instore agents have advise me that this is something that should have been done on the onset of the application process.

Now I have no other choice but to cancel the contract and move over to Vo**com as I need to keep my existing number.

There seems to be a disconnect between the instore and call center agents.
