I've never found accent to be a huge issue in general with first line technical support. It's more like 95% of the time (OK, I've done something dumb now and then) they're going to take me through scripts that are increasingly non-responsive and orthogonal to my problem before promising to call back--which they never do.
If I can get to someone in a US support center, I've just found that they tend to be better enabled to actually address my problem--even if they have a southern accent :-)
