Terrible so far. Charged immediately for 'free course' Offered five 1hr 'free' online courses - entered payment info and redemption code - immediately charged - sent email five times in last two days asking for credit and response - no option for immediate response -just an autogenerated email thanking me and saying someone would contact me in '2 business days.. 1 hr course was okay but many references to jsbin website were outdated and didn't match my screen even though I used all the recommendations - chrome, etc. Onlilne form is only method I can find to contact them; searched google, they use so many different names, some requiring separate id's and passwords. very strange. Names Stackcommerce, GDGT, etc. Funny how the charge was done immediately even though I entered a free redemption code, BUT I have to wait two business days. ie. THURS FRI sat sun MON. It's Saturday now so I hope I hear something by Monday.
