cancelled a reward flight over a month ago....i got an email from ecommerce stating that the refund will take 2 weeks....i got the taxes amount back on my card in about 10 days but its been almost 5 weeks now & i still haven't receive the miles back in my account....calls to the customer service center are unhelpful since they tell me to send an email....sending an email is unhelpful since they don't reply....has anyone else faced a problem recently in getting miles re-credited to their accounts????
