Melted after a few uses, company sent new machine quickly

Used less than 5 times before the hand piece got really hot and started to melt. Tried to return it but the return window closed a week ago. The user manual says there is a warranty but has no information on how to contact them for that warranty. Edit: the company contacted me and has sent out a new machine. they actually were quite helpful...I will edit my review based on the performance of this new machine.
