Poor Bad service

I signed up for a new contract in August (business account/sponsored billing), the sales consultant (Khaya) signed me up on the wrong contract (prepaid instead of the same contract I've signed up for for the past 3yrs. I realized this when I tried to buy data on the app to be added to my monthly bill as I've normally done in the past years, I went to the store to enquire this from the same consultant (Khaya) he acknowledged his mistake and asked me to bring the sim card so that he can replace it with the correct one and sign the correct contract, and informed me that unfortunately I will have to wait for the next month for this contract to be loaded. I went to the store again after my phone was suspended and checked with Khaya again, there were 3 numbers which were loaded in the system. The consultant misrepresented the deal, he said Ill only be paying for one number (0722113233) he said the other number comes as an extra for the promotion they re running. the other number which starts with 066 was eventually cancelled, but the other 2 new numbers are still billed . I was both extra numbers to be removed from my contract and remain with only 07222113233 which is my primary work number paid by my employer.
