Appalling service, no communication for almost a month

Hi I have had the most abysmal service from Absa and have still not received finalisation on a claim three weeks later. I follow up regularly which is very time consuming and I never hear back proactively from the insurer. The car has been standing for 3 weeks and the dealer won’t keep it any longer. This is a fairly straightforward claim so the delay is simply unnecessary and unacceptable. Furthermore the complete lack of communication shows a complete disregard for client service. Why would I continue to insure with such a provider? Why would anyone?
