Staysure Travel Insurance - ignoring my emails sent via Resolver. I was advised last year that, if I needed to reschedule my holiday due to the pandemic there would be no issues in rescheduling my travel insurance. This year when I went to do exactly that I'm treated as if they are doing me a huge favour. Initially I was told I would lose 90% of the money I'd already paid they then said as a gesture of goodwill they would reschedule the insurance for my rearranged holiday next year but it might cost me more. I was told they couldn't do this there and then and that the advisor would call me back in a weeks time, over a week and a half later and no call back. No response to me complaint email and clearly no disregard for their customers whatsoever or the stress and anxiety they are placing on people like myself in what are still troubling and difficult times.
