MTN *****!!!!!!

I never had a contract with Mtn but today morning they graced me with a debit order of R6695, when I call them they tell me I opened 3 contracts were I took 3 s21 sumsung phones and an two iPhones within a space of 3 weeks first one on the 11th of May in western cape and east London while I'm based in joburg . Can you please sort this out fast coz it's really bad for you guys if you can't pick up ***** cases or atlist authenticate ur clients applications
