Call Enbridge, tell them of your problem, tell them that you feel that you might be getting scamed and you would like to have it re-inspected by one of their inspectors. They might charge you the $69 for a sevice call, if it fails, but probably worth the risk. If they "Red Tag" it, they will usually give you 30 days ( this time of the year ) to get it repaired/replaced. It will at least give you a chance to shop around.
Had it done to me - and this is what I did
