AIG Travel Insurance - Cannot make contact -Do not use

I had planned a trip as COVID broke world wide and had to cancel all my bookings including my travel insurance. Instead of asking for a refund I just let them hold the money on my behalf. At no time was there a mention of it lapsing. I travelled again this year. I actually forgot to call and a few days into my trip I realised Id forgotten to update my travel insurance. I messaged them the Saturday and then the Monday. There response says 24 -48 hrs so I wasnt to concerned. By Wednesday I had someone call the call centre, and they could not get through and was advised to leave a message that was never returned. By the Friday of that week I wrote a email to say I would report them to the ombudsman. Immediately I got an email to say that my insurance had lapsed the week before. What poor service to a faithful customer. They will never see my money or future business again
