Proline - received the worst service

Im very dissapointed with the service i received from proline. When i had an accident i went there to fix my car, after 1 week the peice fell off and i messaged a lady from proline telling her about this. She said i should come back and fix it but i never had time because i work 9-5 everyday, she said i musnt worry and come whenever i am free. I then messaged her when I had time to come and the following week we had gone into Covid where everone had to be in lockdown and so i couldnt come. I then messaged them recently and got a response saying they cannot fix it and its unrelated. I then messaged them a week after and complained and a lady said she woud call me back which noone did! the paint job that they did has also come off already! im very very dissapointed
