Just an update - I called SE desk this morning, they verified only 19/20 coupons used
to date, but despite asking a lot of questions, were unable to help. But they did
call me back a few minutes later and gave me the IT support number in Montreal -
apparently it is the French language tech support number ( this does NOT go to India!). As the techie was working through it, he mentioned that they just received
the referral from India.
Problem is not solved yet, but they are "working on it".
But for anyone having website problem, I suggest changing to French, and your
call will go to Montreal right away i/o India.
