Terrible communication with any excuse not to pay the claim

It has taken Santam over 2 months to attend to a claim for my vehicle where someone drove into the back of it. Communication was non-existant unless I chased them for feedback. They have now turned around and refused to pay for a repair to the air bag module (my car now has a permanent air bag warning light on the dashboard) - claiming that it was unrelated to the accident! In what world is an air bag warning light that starts immediately after an accident not related to the accident?!

So I am now meant to take back a vehicle from their appointed repairers with an airbag fault and obivous safety concern! Clearly any excuse to not pay a claim (this is my first claim) and I no longer have any faith that when it comes to paying out, that Santam will do the right thing. There have to be better insurance companies out there and I'm certainly taking my business elsewhere.
