Thermostat failed??

Unfortunately no as when I purchased the snake I purchased also everything else as the shop was offering a set up, that was my mistake. New I mean I got it sealed and it was opened few days ago.

I'd talk to the shop's manager, see if they'll work something out for you. It NEVER hurts to ask. Not if they want your repeat business... And not if they want to avoid having you tell others that you got a bad deal there- one that could have killed your pet.
