Bad service- Activate by Absa

I've been a client with Activate by Absa since Dec 2020. Their service was good when I first join. I had 2 claims for windscreen which they've attended quickly. From last I noticed that my premium is going up even this year. I wrote an email to ask for premium reduction as the value is dropping each year.i never got a respond to my email. I've another 1 and tries to call, I was on hold for very long time. Till this day I've never receive a respond to my email.
