I just received a policy cancelation letter of my insurance with absa.i have a vehicle that is worth more than half a million and I don't know what is going to happen to it should the be a loss on that vehicle as it could now uninsured⁵. Secondly there was supposed to be a notice as these gives me no time at all to get a qoute with other insurers as it s weekend. I am so disappointed with absa.
