ABSA stops Building insurance cover without advising me - WHY

Absa Insurance advised me that there was a problem with the issuing of my Home Owner Building policy as a routine notification. In June 2024 the correspondence advised as follows ......Policy renewal notification -Absa Insurance Company experienced a system issue, which resulted in certain Absa Homeowners Comprehensive Insurance (HOC) policies not sending policy renewal notifications to customers in advance. We are pleased to advise that this issue has now been resolved and that your Absa HOC policy was renewed, effective from its original renewal date on our system. The sum insured increased automatically as per our policy rules. ....... I recceived nothing from ABSA, when I enquired at the end of September 2024 via email I received a reference number BUT no response from ABSA Insurance. When I called them at the begining of October I would told I had NO INSURANCE COVER. HOW is this possbile and when was ABSA going to advise me that they had removed my insurance cover after 20 years on both my bonds and DIDN'T think it was important to notify me?
