No response from call centre

I purchased a Defy fridge little over a month ago with a 5 year guarantee. The water dispensing unit is faulty and needs to be replaced. I called the call centre at least 10 times to arrange but phones are not even answered. I thus cannot even book for my fridge to be fixed for the call is not answered.<br> I left a message with a receptionist of sorts 4 days ago and i was promised someone would call me back for the call cerntre people are \very busy"but i still have had no response."""
