I choose Coverwise insurance for a seven day holiday in the UK. Unfortunately, my wife tweaked her back a few days before we were due to travel and she was advised by the doctor not to go on holiday. Fortunately I was able to renegotiate the holiday dates putting the booking back six months at an additional cost of £91. I contacted Coverwise explaining what I had done and requested a change of insurance date to cover the amended dates. Coverwise were totally unsympathetic and have refused. I will never use this company again as it appears to me they will do anything to make money and are totally unsympathetic to customers needs.
