Bolt **********ly charging my card!!

I frequently use Bolt and since prefer not to carry cash on me, I make use of the in app card payment facility. It was not until recent that I went through my bank statements thoroughly and noticed that there were NUMEROUS unauthorised transactions from Bolt on my card. It comes off as small, unnoticeable amounts like R10, R18 etc but up to three such transactions per day. I am awaiting response from their support team. What I can advise is DO NOT avail your card details on the app and if you already have, go through your bank statements with a fine tooth comb.
