charged for a ride I couldnt request

Hit "request uber" got request failed, same thing happened again and again, I tried at least 4 times. Later, when I was on my way in Lyft, I received a notification that an Uber driver canceled my trip, no idea which one, then I received a receipt $5 charge cancelation fee. There is no way to contact their customer service to explain all that. They refund me with a credit when I hit "I couldnt connect with the driver" in the "help" section. I DONT WANT CREDIT, I WANT REFUND
