Helivac can't send a sticker...let alone a helicopter.

Helivac sounds like a good idea in theory but I fear it is a ****. After numerous phone calls and emails over the space of years I am still to receive any proof of membership. No sticker, card or anything. So, if I were in some sort of accident and unconscious, I would be unable to make use of their supposed helicopters because I have no proof of membership. What is worse is that it is proving impossible to cancel my account. Steer clear of these ********s.
