Unauthorized debits

im so dissapointed with telematics.they called me on 29 to setup a double debit,

I asked why since I'm not in arrears my debit date hasn't approached I then refused and told them to debit the agreed amount of R209,

as agreed they debited that amount on the 29th Nov 2023.but they debited 2more debits on the 30th Nov to make 3 debits within 48hours hows that for the service,
