No feedback from complaint after 13 days

My car insurance premium was increased by 14 % in July despite not having had any claims or any changes to my risk profile. I wasn't notified that I would be receiving an increase (unless it got lost in the post). <br> <br> iWyze advertises that they decrease your premiums with the depreciating value of your car so I phoned the call centre and they offered me an increase of 7 % instead.<br> <br> I spoke to a friend in short term insurance and she confirmed that the depreciation of my car should be more than the 10 % inflation that the car insurance industry works on.<br> <br> So I wrote a complaint to the complaints department of iWyze. Five days later they hadn't responded so I wrote a complaint on hellopeter. They responded on hellopeter promising to call me. A further 8 days later, and I have only received 1 missed call.<br> <br> Interesting to note that iWyze has the highest complaints ratio of 91 % compared to industry average of 37 % on hellopeter.<br> <br> Conversion rate also worst. Possibly due to fact that they don't make an effort to resolve legitimate customer complaints? Just saying...
