Just wondered if anyone else had gone with Swinton? Good company? Bad company?

I'm in the middle of a dispute with them over recieving my proof of no claims...it went off with the signed agreement but now they are saying they haven't recieved it. 2 copies later, they've decided to cancel the insurance and charge me £70 for the pleasure...grrrr! They would drop the charge to £20 if I take out a new policy over the phone, costing £150 more than the quote I accepted!

Strange thing is though, how can they charge me a cancellation fee if they apparently never had the signed agreement and the proof of no claims in the first place?!

In the middle of writing to them, but has anyone else had the same thing with an insurer? Wondering whether to sort it out with them, or go with the even cheaper quote, Bennetts?! ;D
