MTN AND MONDO PLAYNG CAT AND MOUSE WITH ME

MTN's so-called "rewards company", Mondo, contacted me on 28 February 2022 and convinced me that the contract on my mobile router was about to expire. The gentleman concerned, Nico Williams, then offered an MTN deal which he said would not be available from MTN, only from Mondo I accepted the deal however when the router arrived, it was a fixed router and we require a mobile router. I returned the router on 7 March 2022. and while returning it, I found out that the contract on my router still had another year to run!! As this was returned before the cooling off period, I did not expect to be charged but this was not the case. I have contacted Mondo numerous times by email and phone calls. I have physically been into MTN and have been told that I will be credited. Today is 19 April 2022 and I am still waiting for my account to be credited. To add insult to injury, on checking my latest bill, it is outrageously HIGH. I will now have to go into MTN AGAIN and I will not leave until both problems are sorted out. I am very disgusted with MTN and am sorry that I still have contracts running with your company.
