Bad service - charge me double

He came to my suit in downtown to fix my washing machine , after 5 minutes , he said that he won't be able to fix it. and he asked for $65 $2 for parking for only 5 mintues! I paid him and then i called the other centre they fixed it inn 15 mintues for only $55 !! I called him to get a refund , he swore at me!!! and becasue he can not speak english very well , he passed the phone to his son and his son was so rude, he swore at the me too. I will take action against them legally.
