Bad service

I would like to report my utter disappointment in the service received from Absa Insurance regarding the repair of my vehicle.I have been having endless issues since my car was sent to the panelbeater appointed by Absa.it’s been going back and forth since November and I still do not have my car back,nor do I have a courtesy car so I am left stranded without transport,this is my first claim and to say that this is absolutely disappointed in the service is an understatement- all I get are apologies and no action.I’ve requested Managers contact me and not once has any manager bothered to call me back,that is pathetic customer service to say the least
