"Left high and dry"

Had several visits as have a torn tendon in my left shoulder, was recommended keyhole surgery. The operation was first cancelled as the surgeon was in America and rang us to say don’t turn up. We have been given two dates since, both of which have been cancelled, one was on a Saturday and when we got there was informed no ops were carried out on a Saturday. The last appointment we were told a date will be sent for the operation, have heard nothing since. I have been left with a painful shoulder, cannot drive and am feeling hopeless about ever getting this op.
