Provisinal insurance update - increase in premiums

I have received an increase insurance schedule that is effective from 25 December 2018. What disturbs me is that they have increase a premium on both the car that I insure with. I have VW and CHR when I add the inflated increase amount is adds up to 1600 on top of the premium I was paying. Now I argue why did they increase a fee on my CHR Toyota car as since I have joined their insurance I have never claimed. A claim was only processed for the VW Polo which I can honour the increase of 700. So I am utterly ****es that for CHR they increased a premium of an additional 800 . I asked the consultants the reasons thereof...the consultant explains to me that they don't have my details of the previous insurance I had previously before I joined outsurance. I re-iterated on this that previously I was on company car scheme for 5 years nd all vehicles were insured by the company. So why was not these details requested when I joined outsurnace as I gave them and somehow the data got lost a year and half later. So now who's fault is it . I must go back to previously employer inconvenience them to write a letter confirming that I was on company car insurance when their own disorganized consultants lost the data that I gave them. Why must now as customer suffer for their incompetencies .

I asked the consultant why would the previous employer now assist me on this when I literally gave this information when I requested a quote from them. So you tell me why this kind of service is done and why should I keep outsurance when they lost all the data I initially gave them. On top I have repeatedly told them on the CHR Toyotal I have never claimed so how is that I get penalized for 2 cars when I only claimed for one car which is being driven by my parent. Where is the loyalty and delivering customer value services.

I am utterely disappointed.
