Those jokers at AVIVA, get that - AVIVA - wanted to increase my renewal policy by nearly 50% and were most unhelpful in doing any negotiation. The website is pants and I could not do it there so had to use chat. It was like dealing with a toddler in a strop so I have left.
I have gone to other "known" companies direct - not using any comparison sites - and have got the same cover as last year for only £28 more!
It pays to shop around... and avoid AVIVA like the plague.
