extremely bad service provided by the panel beater chosen by my way

was involved in a car accident on the 23rd of Aug and my car was booked to have repairs done with Barloworld coachwork panel beaters Isando by Tshepho Sekome. on the 28th of Oct I took the car there and I had been asked by the repairer to deposit 10% of my access to have the parts ordered which i did . when i dropped off the vehicle the repairer said it would take 7 to 10 working days over sometimes they kept delaying the estimated delivery date saying they needed to order some more parts which i fail to understand because during stripping that is when they check for all damages they can not surely be ordering parts one by one . Called Miway why would they use a panel peater with a service that is not speedy and helpful for their clients especially since Miway is a very big company also made an inquiry yesterday and asked to speak to Tshepho Sekome and he was already left for the day and the consultant said he was sorry to hear my problem and he will call the panel beater and get back to me by 9am today even now I`m still waiting for his call
