Loyalty not considered

I have been a loyal Cell C customer for over 10 years. Recently took out a data contract, and after 3 months needed to migrate to a HIGHER package for extra data. Was told I would have to pay in full for the month on the old contract as well as the new contract.

The consultants were helpful but they could only assist as far as they could. Cell C need to put a protocol in place for rewarding a long standing customer, apart from frivolous offers which aren't exclusive to an old customer
