For what it's worth I think your fermentation is going fine given the circumstance.
I'd suggest that
A - you've slightly under pitched for a higher gravity beer,( a good rule of thumb is that a SG over 1.050 you should pitch 2 packets, )
B - you didn't re hydrate the yeast and
C - SO4 is a fickle beast, and tends to be slower than say, US05, and under attenuate ( Higher FG reading).
I'd keep your temp up at 20 degrees, give it the gentle swirls others have mentioned, and what a few more days. I leave all my beers fermenting for 14 days before cold crashing, so 11 days isn't so bad. I'd suggest US 05 is a better choice for your next version, unless you like what SO4 has brought to the party.
I'm Currently drinking my version of this ( S&W pacific ale). It turned out great, and very clear. The Recipe was 1.5kg light Coopers liquid extract, 1 kg dry wheat extract, and .250kg light DME in 25L to get 4.5% ABV( Oh and I used galaxy to 21 IBU's)
Good Luck!
