Bolt (Taxify) *****s money from my card eceryday

Hello Peter, I requested Bolt on the 16th Jan 20 and used my card details as I did not have cash. Prior to the trip, they deducted R48 apparently that's a pre auth hold, and it should be refunded and when i got off, they took R56. The next day on the 17th I requested Bolt again and the same thing happened, R56 was deducted prior to the trip, and R64 after the trip was finished and then on Saturday morning the 18th without even requesting they deducted R51 and also this morning without requesting their services. So it looks like these people just enjoy taking my money everyday even without requesting. So if the money that was deducted as pre auth prior to the trip, then what are these deductions for because I haven't used their services and I never will again. Never ever put in your card details on Bolt rather use cash. Now I need to cancel the card because of these ridiculous ********** debit orders.
