MTN *****ing clients Monies

I have tried to transition a couple of cell phone contracts to better options as they have come up for renewal / upgrades. Submitted online, and nothing effected.

Yesterday visited the Morningside offices and was told that I cannot upgrade to packages offered at the advertised prices. The reason given by MTN was that i do not qualify for these prices as my account was not migrated to their new system. Therefore, the pricing offered to me was a significantly more expensive option. This must be contravening advertising standards, will report accordingly. Have you heard such nonsense? They further said that they have NO IDEA when i will be migrated to the new system. This means that i must continue paying (included in current billing) for the phone which is fully paid up in the previous 24 month contract - this is theft.
