Poor service

There is completely poor customer service at Bolt. The supp**** number never works. I sent a complaint the other day about one of their drivers who charged me more for a trip. The driver left the meter running even after i had been dropped off. Contacted them immediately to state my case and there has not been any response. I even left a comment on the rating page, which was clear about my concerns and still there is no response. I wonder if this is the right to conduct business. There is no office that attends to our simple complaints and being ill treated. At least DiDi is here these guys must just watch the space. and i would really appreciate getting someone to resolve this matter.
