Dent Doctor (Honeydew) Unclaimed

At the time of writing, Dent Doctor is two weeks over a repair deadline that they set. 1. They did not follow due diligence when quoting - they quoted on a part that is not available (or so they say) 2. My car was with them for a week before I received a notification about this part. Surely a parts order should have been placed on day one? 3. In writing, they confirmed that they were waiting for a bumper. Later I was told that a door was the part they needed. 4. They did not ask nor receive MY authorisation for this new part - this is a massive Consumer Protection Act contravention. 5. They have made no attempt to rectify this situation. As a paying customer, I have been expected to merely just accept this sub-standard service.
