My husband's GP is refusing to complete a claims form to get a refund for the holiday we could not go on because my husband was diagnosed with bowel cancer, had radiotherapy, then major surgery to remove the cancer leaving him with a colostomy. The hospital filled in a form explaining that he could not fly but the insurance want a form from the GP too. The GP has said no but has accepted £35 to write a letter to us explaining that they can't fill out the form. It makes no sense. Any advice? Without the GP support we will lose £3000 and at a really difficult time. I cant understand it.
