Shocking Service!

I bought a Samsung fridge from House & Home in early December last year. They didn't have any in stock and suggested that I take the one off the floor. The fridge continuously makes a very concerning noise. I went to complain at the store and they were suppose to send in a Samsung technician to come look at the fridge but instead they sent some contracting company to collect the fridge and take it to be tested. I did not agree to this and refused to let the fridge be worked on or tested out of my home. This is unacceptable. I bought two Samsung appliances on the same day, paid cash and I would like to either be refunded in full or they must give me the exact same fridge new in the box. The store or Samsung have not contacted me back for over 2 weeks with any feedback, what kind of customer service is this
