Sorry you had a bad time, feeling like you've been stood up by a WG sucks. Landlord is Polish for `I'm terribly sorry but something urgent has come up and I must cancel on you at the last minute'.
Chalk it up to experience then young grasshopper, next time don't put all your eggs in one basket. I could find myself 5 back up numbers for Swindon I reckon. Although EE girls can cancel and be flakey, they're more likely to be sitting around and available for you at the last minute. I recommend Czechs and Hungarians but I've been lucky so far.
