UNSATISFIED - MTN

This one star should actually be no star! MTN and Mondo have totally dropped the ball. They were very eager and called after hours to sell me a router with prompt replies to mails, but after I received it it did not work, and I have had ZERO customer service. I have phoned/emailed and still no working router. They are refusing to cancel the contract as it is after the 10 day cooling off period. Router received on the 24th December 2021. Tried to activate over my leave and assumed it did not work after 24 hours as I was told it was due to me taking it home and not using it at the designated address i had given. When I got back to work on the 3rd January 2022 it still did not work! I called in and was transferred from one department to the other. I tried again on the 4th and was on the phone for approximately 40 min to be told to wait 3-5 working days for my query to be resolved. I asked that the contract be cancelled and explained the entire story and was told to go into my nearest MTN (40km away) and pay a cancellation fee of R2200. I said it had never worked etc and that if they could get it working the same day I would be satisfied. The lady put the phone down as I told her she was not trying to assist the customer. I am not sure if this is a Mondo or MTN issue as Mondo called to do the sale but the internet and contract are done through MTN. I have been with Cell C for over 15 years and should have stuck with the service provider I know and trust. This has been an awful experience and I would not recommend either one to ANYBODY. Vodacom is offering the same deal as MTN and there service has to be better than MTN - GO to them everybody!
