Extremely poor customer service

This is now my second review regarding the service we have received from Defy and Barnards TV and Electrical. We have called Defy everyday for the past 3 weeks regarding a faulty part in our washing machine which is 7 months old. Each day we get the same response that someone will call us back with when they will be coming out to repair the machine. Empty promises have been made on a number of days as they had said that a technician would come out my wife and myself have thus stayed home on these days waiting for a technician who never arrives. This has become extremely frustrating and we no longer know how to deal with this as the only time real action has been taken is when we write a poor review. Very unprofessional, inconvenient and frustrating.
