Useless Service Mondo / Telkom

I was called by Mondo / Telkom early December 2019 offering me 2 Telkom data only deals (4GB at R 100pm each). I excepted the offer and received my sim cards two days later as promised. Since then it has been a nightmare. First off all my sim cards were activated as 1GB, Mondo / Telkom lodged an investigation and found that this was incorrect and it should be 4GB. After phoning every day for 2 weeks and a whole lot of escalating and empty promises the sim cards were activated again but this time only as a 2GB. Phoned again and the problem was escalated. It is now almost the end of January 2020 and still no activated sim cards. I want to cancel my deals with Mondo / Telkom with immediate effect as the sims cards are as useless as Mondos /Telkom Service. I am going to tell everyone I know about this poor poor service and that they should avoid Mondo / Telkom at all costs..... I need urgent feedback from Mondo/ Telkom on when they will pick up their useless sim cards (just as useless as there service)
