An absolute nightmare. So much so, I felt the need to write to the head of Aviva UK, Andrew Moss to explain the details of my experiences. Accurate, with a hint of humour. You can read the letter in full below and even download it to email to friends, should you be experiencing similar issues.
The final outcome of this experience was my direct debit still wasn't change, so I cancelled my policy. Which will be accompanied by further cancellations when the others comes up for renewal. I don't normally rant, but on this occasion i felt it was the only way to help others considering Aviva or those who have had similar experiences. As of the evening of 22nd July I still haven't heard back.
