Brand New Fridge - not right from the word go!

I purchased a new fridge from House and Home on 11th January, which was delivered on 13th January, 2018. The front feet could not be adjusted on one side and the door for the fridge compartment kept opening. So here was my new fridge held closed by masking tape. I phoned House & Home on 15th January and a gentleman came out, hammered the foot to get it loose and when I mentioned the door, he opened it and pulled the seal off which was held on by "fresh air". He then went and got glue and stuck it back. I was horrified as this was a brand new fridge. It was icing up but he turned it down from 3 to 2 and told me to give it a few days and turn it up. I did this and it still ices up, that now it is turned down to 1 1/2. The top drawer in the freezer catches on the second draw. I phoned House & Home on 2nd February, 2018, they told me they would get hold of Defy and they would phone me, nothing happened, on 7th February, I phoned again and eventually got a reference from Defy. Once again nothing has happened. As this is a new fridge that has never been 100%, I have requested a new one as a replacement.

I must say I am totally disillusioned.
