Useless insurance

I bought a mini cooper s roadster jcw in 2021. I took out comprehensive cover with AUTO AND GENERAL. In 2025 my first assistance requested from them during heavy rains and floods I encountered numerous potholes damages over time causing damage to my car. It became a nightmare. 1st I was asked to have an app to submit a claim. 3 failed attempts by trying to upload pics on their app. Numerous requests made to send me to a inspection centre. Eventually after 1 and a half month. I was directed to a centre where a visual inspection was done in 5 mins and said nothing wrong with car. Despite having all warning lights on Aircon pipe damaged severe vibration while driving. Then I complained to broker who intervened. Same assessment centre calls me want to book my car in a week later to have a diagnostic done in 4 days time. I requested that I would take it to SMG OR AN RMI WORKSHOP and I will pay and provide proof. It was agreed by an executive once done the claims department refused to reimburse me and don't want to accept the diagnostic report by the workshop that carried it out. After much disputes was I reimbursed. Now the same initial assessment centre wants my car back to do a proper inspection almost 3 months later without being of any help. So my car is not affected by floods horrible roads. Today 24 March 2025 I must take my car in for inspection
