False assessment

I have submitted a claim to Auto and General in January 2020 for appliances that got damaged due loadshedding. They collected the items and according to them it is faulty due to normal wear and tear. I then took it to an independent company after the lockdown we encountered in June 2020 and they found that one of the 4 items were normal wear and tear and the other 3 items were due to power surges. Claim no ***/7. I have send this info to Lynette (***) that work with claims on 22 June 2020 and she did open the mail but didn't respond as of yet

Please help
