My attempts to renew on-line only lead me to the page of 'Policy Expert Menu', and a large message 'the page you're looking for can't be reached'.
All attempts to contact you on-line from the headings or from your Main web page had the same result.
I eventually renewed by phone, and the service then was quite satisfactory (though I am 94 and quite deaf so that phone conversations are quite difficult for me). I then got confirmation of my renewal, and links to take me to the details. However, the links simply lead me to the same menu and message. I am having no difficulty with any other links and pages, from other sources, so my computer is behaving quite normally.
I have complained about this difficulty and I have had quite sympathetic responses, but no improvement in your IT performance.. Hence my 2* rating. I suspect the insurance policy works quite well, though I have not had need to test it (and I hope I shan't have cause to in the future).
I find this very frustrating, and if I had known the difficulty I was to encounter I would probably have changed my insurer, though I have insured with you for several years now. However, since I can't get connections to the details of my insurance, I would be glad to have a paper copy.
