As far as I know, there is no reason that S. pyogenes cannot develop resistance to amoxicillin. This antibiotic is susceptible to beta-lactamases. The bigger question is: Are you sure that it is S. pyogenes? Has your doctor made a culture? Has he done a sensitivity to determine antibiotic susceptibilities? If not, I recommend that you insist on it.
