Do not even think about taking contract with them.

I took out a black friday contract MTN data sim card of R199 in November, I was told that if I cancel within 10 days of receipt then I won't be charged any usage fees or cancelation fees, I received sim in December, I was not able to use data as my devices were not supported, I then contacted MTN and Mondo in order for them to cancel my contract, the cancelation went through in December, I was then charged R301.70 for December for what I don't know, January my account was debited again R1062.74 for cancelation which I was told that I don't have to pay as the contract was canceled within 10 days. I have been requesting for a refund and making contacts with Mondo and MTN both giving me different stories, Mondo today said I will not get a refund as I did use the data, MTN can't see any usage on their side as they confirmed that Mondo has to pass credit from their side.
