vodacom contract phone

i had a contract with vodacom, i was paying for the identification or cell number to appear and also extra data bundles, i called vodacom between january and february to ask that this service be disabled, and i spoke to a consultant who assured me that the non-compulsory services would be removed as i requested but to my suprise they continued deducting for the 2 services i cancelled, i called later around april and asked for a team leader and i spoke to bulelani who said they would call me back, to this day i have not been called and i have been waiting for the refund for those etra data bundles and identification of cell number, I will not be using vodacom again in my life
