Ripping People OFF !!!

Mondo Mobile is a ****... I saw a debit order for R1500. I don't understand why you guys debited when I received a confirmation from MTN that R478 would be debited There is nothing on my contract I never signed up for this Can someone please contact me and explain what is going on If this is not a mistake I'd rather cancel with you guys reverse the R1500 and then you can fetch your phone because this is a rip-off ... Your site is not use-friendly and cant get through to anyone on the chat or send an email!!!!
