Delays and ignored

I paid a good amount for the parts for my AEG repair to be imported and waited 3 months for them to arrive. When they arrived I had to beg for an agent to be appointed to install. After a further month, the service provider installed but did not Programme the machine. He promised to come back after 3 days to Programme. Now, 3 months after the part arrived, it has still not been programmed and my emails and phone calls to Eletrolux are just ignored. I want my money back and I’ll buy another machine make.
