Extremely terrible service after 3 years

I requested a callback from the retentions Department but nobody calls me back and I am absolutely frustrated by this.

I've had my netstar tracker for 3 years now and I was told when I got it that there will never be any increases but you guys now send me a letter to increase my premium and I find this absurd.

Considering that I am now working from home and I drive around 150 km a month maximum I found it ridiculous that only now you guys want to increase my premium.

And when I requested a callback nobody had the decency to give me a call at my requested time

I will not be continuing this policy if you guys will be increasing the premium considering I'm hardly driving and if this is the case please call to assist cancellation since you guys couldn't assist in calling for retention
