Vodacom does not honour contractual rates and unable to rectify

I have spend hours on the phone to the call centre, as well as a visit to a store. For months now I am being charged the rate without discount app**** despite neither of the contracts having reached the end of the initial 24 months contract. All I have for my trouble is a list of reference numbers. Happens every 12 months or so. Pathetic to say the least and will definitely not renew any contracts with this lot again....ever.

Vodacom you are *****ing my money on a monthly basis and I want ot back!!
