Huge Double Gourmet Oven that Does not work straight from Supplier

<p>Bought 2 double ovens from Defy supplier, one works but is starting to rust, second one only installed two weeks ago, top oven never went on, Technician came out blaming store saying they disconnected it. A day later trying to roast chicken, bottom oven never reaches temperature, same Technician comes out again saying bottom wires not connected, same evening try to make chicken again, selecting top and bottom element no fan, yet Fan goes on in Super loud mode, rattling the racks and once again - oven does not reach temperature. Same Technician comes out now its a different story according to him. All we ask is for a new unit as this one that has never been used as Technician can confirm as he had to connect all the wires on various occassions is no being opened and tampered with all the time. Supplier says he is a Defy Technician. We have our receipt where our guarentee is expiring 10 December 2016 and Technician confirming we have not used this unit ever yet supplier refuses and rather wants all these repairs to happen. This oven never worked straight from being bought. We are so unhappy, Technician never calls beforehand to set up appointment, just rocks up when we are at work and then have to rush back home this happening on more than one occassion, Besides the unprofessional service we still sit with a unit that cannot be used. Supplier buying time until guarentee no longer valid. New owner of Outlet says he is doing us a favour to send a technician out, all i know is I bought two Defy Gourmet Double ovens , one rusting inside and the other not working - i have nothing to do with change of owners as I have my valid receipt and broken units, </p>
