Missing cushion

I bought couches in Jan 20 - 1 part (2 seater) was faulty. They collected in March. Upon collection their driver bumped my car. Went to the police station opened a case he admitted & promised to compensate me. In April he made 1 payment, said he didn't have income due to being at home. That was the last I heard from him. I had to contact the store in July checking how far they were with the repairs. Was told they had a backlog due to lockdown. My couch was only delivered on the 31 Aug n cushion missing. The driver promised to bring it the next day. I am still waiting. Now their guy is afraid to come deliver the cushion because he has been unreliable. There is no 1 willing to help. They just don't care about their customer. The only time u matter is when u are still thinking of buying. They very good at convincing. Their after service is EXTREMELY BAD. Never have i ever gotten just bad customer anywhere. Oh by the way its ROCHESTER MAPONYA
