Beekman Canopy Damaged my car and the Canopy

Bought a Beekman canopy in Sept 2021. Fitment was conducted and handed over to me. About a month later I noticed that on the corner of my cab there was paint that was peeling off. On closer inspection I noted there was a dent on both passenger and drivers side on the rear of the cab. There is no possible way that the damage could have occurred with the canopy fitted. I raised this with Beekman and they denied all wrong doing say the canopy is in perfect condition. I then took the canopy to many industry experts such as panel beaters and dealers and the all agreed the damage was a result of the canopy fitment. In fact they pointed out maybe 20 issues inside the canopy where repairs had taken place to fit the damaged canopy and hide the damage from the casual observer. I wrote a report around and submitted this to Beekman who has agreed the canopy now is in a terrible state but still claims this is due to transportation of the canopy to the fitment center, which is rubbish as the damage is on the upper level of the shelf and not on the underside of the shelf. Beekman refuses to acknowledge that the product they fitted was damaged and inferior and that the fitment process damaged my car despite a report and evidence submitted the is clear as daylight. Their workmanship is poor. I have been dealing with Beekman now since 10 November 2021 trying to resolve this and all they do is play cat and mouse and make excuses when they get caught out.
