REPAIR TO UNDERCOUNTER OVEN

On the 7/8/13 I purchased an Samsung undercounter oven and hob .On the 7/8/2015 the oven stopped working, I reported it to Makro, who reported it to Samsung who phoned with the reference no ***<br> a technician arrived on the 11/8/2015 and said the switch had burnt out, but I also needed a new oven seal<br> and two new knobs as they had melted.<br> That was the last time I have heard from them. There has been no replies to my SMS to *** and ***.<br> Very Disappointed in the after sales service. I will not refer them or be buying any Samsung products
