Sold a product I cannot use by MONDO rewards and Poor service from MTN customer care as a follow up

I bought an MTN contract through MONDO REWARDS. If MTN are going to do business and allow a third party provider to sell their products, they should ensure that the sales people are properly trained. I was sold a product that I cannot use. What I was told I was buying, and how it works are two very different things. Not realising MONDA REWARDS is a third party, I called MTN directly to cancel this new contract, as it does not work the way I was told it works. First I held on the line forever as they are "experiencing high call volumes". Eventually I speak to someone in customer care. Anyhow, after a few minutes on the phone she transferred me to Cancelations. After redoing all the security checks for the second time, they tell me they can't help me as I am trying to cancel during the cooling off period and send me back to customer care. The consultants attitude stank. Now for the third time I have to deal with someone with an attitude and a poor level of customer service. After doing the security checks for a 3rd time she says she is going to send me back to cancellations. Now I just know I am going to get the run-around. It dawns on me that MTN record their calls, so why can't I too? I then decide to tell her that while she is recording the call, I am now also recording the call and WOW, what a turn around in effort and attitude, it was suddenly like I was speaking to an entirely different person. Makes me think MTN allow poor service, shocking customer experience and I bet unless there is a dispute of some nature they likely never listen to those calls for service and training purposes. They really should, as their call center agents level of service, customer care and professionalism is shocking!!!! And the only reason anyone will care, or I will hear back from someone is because I put a negative review on Hellopeter. If it wasn't for that, MTN would not care.
