Dissatisfied client

Their service is pathetic to put it lightly I am totally disappointed that a simple issue cannot be resolved. I upgraded my contracts through retention on black Friday. It is supposed to be the following: ‪10‬gb + 150min - R79 ‪20‬gb - R99. I am receiving the normal allocation and at more than the full price. R179 no additional data or airtime R199 no additional data Now what is confusing is that the normal price for "made for me S" is R99 Sim only and I am paying more for a black Friday special and I am not even receiving the added benefit. When I phone retention they say it's customer care issue and customer care says it's retention issue. It takes almost a hour to get to Retentions department and I get promises and nothing happens. I have been trying to resolve this issues for the last 3 months approximately 20 calls If this is the leading network in South Africa then how must be the others performing. They actually need less than one star
