Warning against MTN Rewardsco

I just want to warn users against MTN Rewardsco. and MTN itself, with all their sweet and kind stories. On 11 October 2023, a person from MTN Rewardco contacted me, to find out whether I wanted to upgrade my existing contract. I informed him that my upgrading was due at the end of Nov 2023.to which he responded that, I can already upgrade it "at this stage"(October 2023). I asked him explicitly if there were any penalties involved, to which he rep**** that there were "no penalties involved". (I also want to mention that I didn't really upgrade either, because I took a cheaper contract.) End of Nov 2023 I received a bill from Mtn on which I have to pay for both the new and old contract's . I contacted Mtn on 1 Dec 2023 to which they rep**** , I should rather contact MTN Rewardsco myself. MTN Rewardsco also rep**** they would investigated the conversation of 11 October 2023 , to see if I had been "deceived/misleaded. After a week I called them again and (MTN Rewardsco) rep**** that I had indeed been deceived/misleaded. The lady confirmed that a credit note was logged in for management for reimbur*****t. During mid-Dec 2023 I called them again , just to know when the amount will be credited to my account. I was then informed that management is on vacation till the 2 Jan 2024 . This morning(9 Jan. 2024) I again called MTN Rewardsco and I was then informed that I had to sorted the matter out with MTN myself. I called MTN themself, just to learned that I have to sorted out the matter with MTN Rewardco because they have to make the refund. Again I contacted MTN Rewardsco and the lady informed me that she will now send the claim to their management because the personal are only now returned back from holiday. She also mentioned ,that no claim whatsoever has been submitted before today. She also informed me that I must wait for another 14 days for the out come. MTN however is the people that have to send out the accounts but they wash their hands in innocence. Definetly it seems with MTN Rewardco you don't really get a step forward. Never in my life again I will enter into any contract with MTN. I also want to mention that my son fell into the same trap and is also still waiting for his account to be reimbursed. In conclusion I want to confirm that I have a reference no. for each and every conversation but no one of the companies want to know if you have got a reference no or not. It is thus very clear and before hand that the one hand is not knowing what the other hand is doing.
