Auto & General is broken

My home insurance premium has increased nearly 50% for no apparent reason, from around R400pm to around R600 pm. Insured value has remained unchanged and I have made no claims in the past year. And a car which has been covered for nearly a year has now apparently has comprehensive cover denied according to the following message that I keep receiving from A&G "Good day. Your Auto & General self-inspection is still outstanding and will affect your cover. Click here https://bit.ly/3m..... for more info. Ins&FSP" I have called A&G to try to fix this (what a mission) and get told to ignore it because a self inspection is not outstanding but the next day I get the same threat that I no longer have comprehensive cover. Don't know what else to do other than change insurers which I now plan to do after many years with A&G.
