I paid almost $500 for my machine to be fixed

I had to take it back 3 times!!!

Still Its not picking up or working at all

and still they will not give me my money back!!!! even though it has been under 90 days they're not they're not standing by their own Policy...

I've been jerked around and lied to by many of th!!!!eir employees and I'm sick of it
