Poor service at ridiculous monthly rates

My husbands car was taken to a dealership for repairs following a MINOR accident. It is now 6 months later and still no vehicle, not even an estimated time for completion- citing that parts needed to be ordered. This was ONLY done in February this year after numerous follow-ups. Discovery never followed up on their side until I started asking questions. Its now another 3 weeks after a very rude email about how everyone in the country is struggling with a backlog. Backlogs are one thing, but 6 months!! And no feedback?? Bitterly disappointed
