AEG faulty appliances and no after sales service

We purchased a brand new double door fridge 5 months ago. Two weeks ago the power started tripping every few hours and we paid for an electrician to figure out it was our brand new fridge causing the tripping. AEG then sent out a technician who informed us it was the element in the fridge. He then disconnected this and told us he would order another one. The freezer then stopped working at all and of course we lost all our produce. We have now been told that we will have to wait an additional 15 days for a replacement. Who can wait that long for a fridge and what happens to all our food in the meantime. It seems to be a running problem with AEG and there is no after sales service. This will be absolute last time we purchase one of their products. I have taken to Instagram and Facebook, I am going to report them to the Ombudsman and if we have to, seek legal assistance.
