I bought a stove and oven and the stove was installed and within a month the glass cracked and we have logged a call on the 2nd December 2021 and was promised it will be fixed before the 25th December 2021. The guy came to take the part number and never returned. We have been calling every week and been sent around with the excuse due to covid 19 the parts are blocked from coming in to the country. Up until today the same excuse was provided and it has been more then 2 months and they will not contact us to tell us anything we have to waste airtime and call. This is really disapointing and I regret buying this brand.
