So. I was with them for 1 year after the driving app discounted my insurance down to an okay price.. 2nd year, going well up until a month before my renewal.. I brought a new car less than a month before my policy was due to renew - switching my ncb onto the newer vehicle, they failed to tell me this would result in my renewal, at the end of that month being split into 2 years and 1 year ncb instead of 3 years... great.. one whole year wasted. I swallowed that pill and gave them the benefit of the doubt.. Roll on my last renewal (22nd August). I received a letter, that despite now having 3 years no claims, and the 1 year on my old car, which is wasted.. that my insurance had gone up £60 a month, almost £700 over the entire year. I called to question this, the response was oh you've added breakdown cover.. I had my policy open in front of me, I hadn't, especially since I pay for breakdown separately.. They then went on to tell me I had added modifications to my vehicle.. again I had policy open in front of me, I had no modifications added to the vehicle nor policy. He couldn't explain to me why, with an extra years no claims bonus the price had gone up, trying to sell me down the path of I had done something to increase this price - I was then told this price was fixed, they wouldn't match even offer to match it with my current quote. To give you an idea of the costs, they were quoting an existing customer of what would have been a 3rd year with them £3100 for a 1.6l renault clio, for a 24 year old driver with no prior convictions and 4 years ncb. I emailed their customer service and complaints team on the 22nd July, I received an acknowledgement email on the 29th. Over a month later not a single word from them. I wish I had cancelled my policy on buying my new car in my second year and gone with Hastings or Admiral. I would have exactly the same amount of NCB, and I wouldn't be chasing for proof of NCB and an explanation on how they can increase prices by over 20% with no reason. Maybe I'll pop into their head office in London on my next day off, see if they reply to me in person?
