Angry and disgusted

I have been debited from my account with no notification from CREDITGAIN ********** LFSA -180430 and LOANSUNL ********** 80426 whatsoever of R397 and R395 from this place and I never gave any permission to do so . I have no budget for this amount to come off and I'm very upset to have these two debits come off without my knowledge. I want it to be reimbursed because I need my money back. It is not a small amount.I want my money back asap
