ABSA Insurance unusually slow with payment

I've been an ABSA customer for 3 decades, and my house insurance has been with ABSA since 2013. Usually dealing with ABSA Insurance is very efficient, but not this year. I submitted a claim on 15 October. I had to follow up every week either by email or phone, and submitted my documents a few times. Eventually I received and signed a Cash Settlement Form on 30 October, which I returned promptly. Since then I haven't received any communication, nor has the money been paid into my account. I can't believe it takes this long - usually everything is sorted within a couple of weeks. What is the hold up? The claim number is ***.
