I missed this post.Yeah, but it's a straight road
But seriously, why did you contact Glasgow SC and not go straight on to Roadside Assistance?
I can't really just turn up (tow truck or driving) at Glasgow SC as I need to arrange a loan car with them if at all possible that I pick up at the same time (being 85 miles away). Also they then said as I am over 50 miles blah blah - this turned out to be incorrect but took me a while to check it.
Lastly they make the roadside assistance service clear that it is for emergencies when stuck on a road, and my car was in my drive so may not have been happy with that.
