Incredible is Disconnected

I purchased an HP #Laserjet M111CW in May. When printing smoke started coming from the printer. Even though I'd purchased it online I had to physically take it back to the store (Sandton City where the tech staff was just awful; the staff also have no authority to make a decision and have to refer the problem to Head Office; they should learn something about empowering staff to solve client problems). They have possession of the unit, have escalated it and escalated the issue and there is still no resolution (it is now mid July).
