Highly disappointed customer.

I recently bought a Defy gas hob. From the very beginning I was having problems with it. Everytime I lodge a complain defy would send they guy out to see the problem. The 1 switch was jammed n as a result the valve inside was broken. All the nozzles inside keeps on getting block. This hob is not practical at all. I would highly recommend not to buy this glass gas hob as it's difficult to maintain n not practical at all. As this stage I'm so frustrated I could just throw that hob in the bin. BTW the technician that came out seems like he was forced to come out n sort the hob. Was extremely unfriendly n not very helpful. This is the last I will ever buy a Defy appliance ever again.
