Never get anything from teljoy!!

Ive sent in my playstation to get cleaned up inside cause it was getting warm when i play games ive been waiting 3 weeks to get the damn thing back. When i got it back the ps isnt turning on anymore but when i gave it to them it was working but just getting warm when playing games... Another thing as i opened the plastic cover above the hdd it was still full of dust and wasnt cleaned of dust so witch means its still going to overheat wth teljoy you guys suck
