I would also write to them. It might not change the outcome, but companies need to know what their customers think, - and it will make you feel better. I wrote to Domestic and General when they increased my boiler cover from £8.90 per month, to over £25.00. I had first queried it on the phone, and it was quickly reduced to £18.00. Too little too late, as I had found a lower price than that. I got a reply to my letter, giving the reasons why it had gone up so much ( greed to some extent), but there was nothing they could do. No mention of the fact that, when pushed, they did reduce it somewhat. Strange how companies like our feedback, when it's positive.
