ABSA iDirect Insurance not responding to emails and not picking up calls!!!

I've had my car insurance with Absa iDirect since 2016 and since December 2024 I've been trying to get hold of them. I've called numerous time and on hold for over 50 minutes and they are not responding my my emails. I need to update details on my policy. My premium and excess was increased so much last month and I can't even get through to the review department to query this. I'm very disappointed with this poor customer service after so many years with ABSA. I've been getting quotes from other insurance companies but I can't even cancel because they're not picking up my calls.
