Poor Service

I had been using Bolt for a while now. But, the other I requested a ride from Lynnwood to TheresaPark and all my requests are made with my card. On our way the driver asks me which route to take, and I kindly said whatever is shown on the app. He says to me can I pay cash and I explain I used my card. He said he will cancel the ride and I will get my money back, and I pay him cash. Mind you, that time, he is on a "reserve" and wanted money for petrol. I did let him cancel the ride and I gave him cash, which cleared in my bank account and I also had to pay for tall gates. Another incident happened where the driver was on "reserve" and this time I had requested a cash payment. He also did the same as the first driver asking me the routes and also pay the tall gate. With this second driver, he asks me how much was the ride and I told him and said you look it up and on my drop off destination he says the rider is short because the amount went up My question was why would I pay the amount that says the ride was a specific amount, arrive at my destination, and the amount suddenly changed?? I think Bolt must have a better service to provide for their customers and make the app user friendly so that we don't argue with drivers who might in turn harm us
