Terrible customer service and additional damage to my car during repair

Very bad treatment from Giselle Smit the customer relations manager. She confirmed repair and completion of my car but when I came to collect it, it was not ready. She denied having sent that communication and refused to pay my refund for unnecessary Uber trips. They also damaged my door handle cover and are now dodging to replace it. They recalled all emails confirming this. But I’ve retrieved them all.
