take it to the top
Just like handleturning, I've been through DSA at least 12 times and never had one ounce of a problem.
If the MD is as good as he says, however, customers who have not had a pleasant experience should address their concerns to him and expect a prompt reply.
Although I am a proud adopted Doncastrian, I always wondered about the potential catchment, what with LBA, MAN, HUY and EMA being reasonably nearby.
DSA's USP (unique selling point) really should be its smallness, convenience and friendliness - the road access isn't that bad, and public transport is adequate. Poor staff attitude (which I suspect is not that common) should be addressed at once.
