Unfair promotional offer

Telkom Mobile has a *123# Monice offer. Different customers get different offers. One customer will get an offer of R200 Data for 7 days. Another customer will get an offer of R50 data for 30 days. How fair is this? Why are customers being treated differently? Why am I being discriminated against? All customers should be treated the same? I now have to spend R600 on Data per month, whereas my friends spend only R50. WHY??? Point number 2: I called Telkom on Sunday 13th January to query this and the Consultant couldnt give me any answers. I spoke to Khanyisile. Since she couldnt give me answers. I then asked for a Manager. Apparently the Manager (Thembelihle) was on another call and would call me back later on Sunday to handle my query. I am still waiting for the call back 3 days later? Telkom, if you dont resolve this query by Friday the 18th of January I will have no choice but to move back to Vodacom. I moved to Telkom for the affordable Data but now I see you discriminate against certain customers. I am leaving if I dont get the same Data offers as other customers.
