To be honest until the budget airline bubble bursts there will always be problems with handling agents.
Aircraft handling has gone down the pan over the last few years. There is no best handling agent at BHX. If you have to deal with all of them then you come to realise that they are all on a par. Maybe the airlines will wise up (doubtful) The pilots complain enough, you would think that they would have some say.
I don't care where the station manager is from or how good he is supposed to be. Nothing will change at Swissport. When they say he's the best they usually mean best for company profits.
None of them give a damn about the staff. That being the case there is no chance in hell of a decent service on the ramp.
