Double charged for 1 trip!!!

I have never been so annoyed and disappointed by the services provided by this Bolt app.

This morning I requested a ride for my younger brother and paid with my card, to my discovery, I was told the driver at the end of the trip requested money from my brother which he would need to use coming back home. When i call the driver with numbers on the app, it noted " does not exist". called using the app, no avail either. tried contacting the support center number unavailable. How on earth are we suppose to get help when your not available ? response to site chats is after a week or so I will be deactivating my account!!!
