Unauthorised debit

In the period of 1 week I have disputed over 3 unauthorised debit orders from capitec. Just this week only from people I dont even know they are not even using real words for their company name. Was upset me more is i just found another 1 today when I log in into my remote banking from dvotion . I don't know who this is and I did authorised this debit of r75 and the capitec app does not give me option to dispute this bedit so that I will have my money back. And the banks are always full these days some of us do not have the time to sit around in this long ques. Get this sported out need to dispute this and get my money back on tha app like I always do when you allow debit that I did not authorised.
