Sounds like they crossthreaded it and/or tightened it with an air wrench.
Inconceivably stupid, I know, but stuff like that seems to happen every
time I let a (non-LBC) garage touch my MG, which isn't often. I had a
certificate for an oil change at one of those specialty places -- what a
mistake. They cross-threaded the oil filter and when it fired up it blew
4 quarts all over their bay. Sure, it was their floor that got messed up,
but it also soaked the block, the inner wing, crossmember, etc.
For my drain plug I usually use a large adjustable wrench (spanner to
you?). Not a crescent wrench, but the kind with parallel jaws at a right
angle to the handle. It gets a good grip and has a long handle for
leverage. If the head is too bunged up, you can file on two parallel
flats until they are clean, tighten up the wrench, and use a hammer on
the end. Frequently a sudden impact, if imparted without slipping and
damaging the head, will jar it loose where steady pressure won't.
Good luck. You might want to take a tap to the threads and buy a new plug
when you get it loose. Use a magnet to retrieve the filings from the tap.
