Not sure if this is the right place to ask this

I'm trying to book a DONE ticket for a July 22nd departure from BOS to LHR on BA. I'm booking this through a travel agent locally as I didn't feel like dealing with the hassle. As some of you have noted, the BA desk seems to be pretty slow, and they still haven't gotten back to my agent about pricing, etc, so I can actually pay for it. Should I..

1) Keep waiting?

2) call the desk myself?

3) Go with AA? (I'd rather not fly AA...)

Apologies in advance if this is the wrong place to ask.
