If you've done nothing wrong (and 91 days is perfectly fine as it was due to flight delays that you say are documented) and don't intend to do anything wrong, the callng the embassy shouldn't be a problem.
In all fairness, "random" people off the internet are likely to give better information than the US consulate. The best approach is to make the people a bit less random by posting on a specialist immigration forum, which the OP has just done.
