Completely fed up with poor client service

I am so frustrated with MTN and completely unsatisfied with their customer services. I received a call from MTN Rewardsco offering me a data package together with a airtime package. I confirmed the offer and verified my banking details so that the pro rata debit order could be processed in the interim. . On Monday, 16 March 2020 I received two simcards via DSV Courier services. I was surprised to received 2 separate simcards as I was under the impression that both packages would be loaded on to 1 simcard. I visited my nearest MTN branch for assistance to no avail. I was referred to another MTN branch for assistance and was advised that I have to phone MTN Rewardsco as nothing can be done from their side. I was shocked. I phoned MTN Rewardsco, which to say the least, was a complete struggle. I eventually managed to reach a consultant who assisted me in cancelling the AIRTIME package. The reference that I received for the cancellation was J0822. The consultant further advised that I have to do a Number for Life, and provided me with the department's contact number. Again, such a struggle to reach a consultant who could assist. Eventually I was assisted after holding the line for almost 10min. I explained that I cancelled the Airtime package and that I would like to keep the data package with my present number. The new sim number together with various security checks were done, and at last the Number for Life was done. The consultant confirmed that everything was in order and that the data package was loaded. After the telephone call I checked and realized that the AIRTIME package was loaded and not the DATA package. One can surely understand my frustration at this point. I do not even want to try and phone again for assistance because the incompetence is shocking to say the least. I cannot even visit a branch as no assistance will be given.... Completely fed up!!!!!!
