Unwarranted premium increase and bad service.

So Discovery out of the blue decided increase my monthly premiums starting from February. With some nonessential explanation about things that I believe have nothing to do with me. Keep in mind that the annual review and high probability of an increase again in September is on the horizon. Yesterday, I send them a tweet and the responded via DM and informed me that they’re only increasing premiums of those that had several claims in the last three years. I’ve only had two claims in the last two years that I’ve been with Discovery. I am not sure if that could be construed as several. A scratch on the door as well as a windscreen chip(which was fixed and never replaced) I’ve asked them to have their consultants phone me and I am still waiting. I am extremely disappointed and disheartened by this. I am even considering switching to another insurance. I do not believe that what Discovery is doing falls under TCF. In fact I am annoyed and I won’t be recommending Discovery insurance to anyone.
