Defy sparkles with its lack of service!!!

I logged a call on 21/5/2020, reference ***, for a Defy stove which needs repairs. A technician was on site to asses the work to be done. II had followed up three times to no avail. On 23/6/2020, the call centre indicated that the parts were released on the 22nd, and that the technician would be on site to repair on Monday 29/6/2020. The day came and went, and no technician, no repairs. Shocking that it takes five weeks to repair an oven. I could have installed a number of other makes in the meantime.
