Hide and sick and lies about a ********** purchase

So after a ********** purchase that took place on my account Game goes on and claim that the query was resolved on hellopeter which was a lie, and that is not the only lie that I have been told by this business, whet I communicated with when I received an sms about the purchase I was told that it happened in Durban, now that I am disputing their finding that I am liable for the purchase, their person with a name mishkah peterson is telling me that the purchase was done online, now if that is the case why was it not canceled because I called immediately after the purchase was done, and I was given an impression that it done in-store in Durban, if I was made aware I would have simply canceled the online order
