Defy oven digital switch

A Defy technician replaced a faulty Digital timer switch on a Defy oven. I failed to let it work: no MENU to select from appeared. I requested help from Defy at ***. The only response I got was a demand for a COC and all my emails were ignored. The last two times Defy assisted, the never required a COC and this time it was part of the previous problem with a faulty switch. I am happy to sat that *** assisted in resolving the lack of email communication with service @ defy.

The defy user manuals are written in bad incomplete language. Eventually the problem is that the buttons of the Digital timer must be held in quite a number of unknown seconds before the menu appears. I still have problems managing the digital timer and find it illogically user unfriendly. Thanks, Jan
