Bad/pathetic service

I have been having endless problems with my Defy fridge. A technician Mohamed has been sent out to have the fridge fixed within less than 2 days the fridge stopped working. They once again sent out the very same technician to have the fridge fixed it has since been 3 weeks and i have not had any response from them. I have requested that i be refunded or that my fridge be replaced i have made numerous telephone calls with absolutely no assistance. I was also advised that someone would call me back but to this day no one has called me back. The fridge i purchased is still under guanrantee and since the purchase of this fridge i have been having problems. The service from Defy employees is pathetic as they have no manner in speaking to customers. I am a very unhappy customer with Defy products as im am now sitting with two Defy fridges that are not working.Im still waiting for Gail and Eddie Knipe to call me back. Very sad to know that Dedy customers are being treated in this manner. Reference numbers: 799595, 834417
