Increases!

So I received an email from Virgin Insurance informing me my premium will be increased. This is due to panel beating costs linked to inflation and upping my home cover by 15%. I am now paying considerably more for insurance. I have never claimed from them. I phoned the call centre and got put straight through to cancellations where no help was provided. I seem to be being charged more than 1 admin fee which could not be explained to me. I informed them that all my assets covered have actually depreciated over the year, so how can they increase my premium? I went on to the website earlier to update a few particulars of my cover and there when you agree to update a message pops up specifically informing you that your premiums will not change for the FIRST TWO YEARS! This is an utter lie, both my car's insurance went up. the guy on the phone told me it was in my terms and conditions sent to me via email and I what on the website isn't binding and that is a mistake what was shown to me. The phone call was made at exactly 11:50:15am 02/07/2015. He didn't seem bothered to keep my business either. I am actively looking at alternative insurance.
