refund request for ********** activity on card

i woke up to a notification of a ride that was approved by my bank saying that i had requested a ride on bolt whereas i never requested a ride on that day and the previous day i had requested and did a cash payment then to my surprise next morning i find a payment confirmation that i have requested a ride and was billed for something i did not request ...i logged a refund request with bolt support to my surprise i was infirmed that there where 5 more other people that we using the same card details as mine and bolt never cared to confirm this with me as the original card owner ..instead of a refund i was advised that they will not be able to assist and that i should keep my card safe ,.,I'm very disappointed with the service that i got from bolt as i think they should have been able to see that the ride request did not come from my app and they should take it up with the person who requested with a card that does not belong to them ...as proof I submitted bank statement card details but bolt still refuses to assist I'm appalled by their service after using them for so long only to find that they would just let it be if someone does such things with card details or personal information
