Expired Argos links

I'm confused by two links on CJ's Argos scheme that appear to have expired, even though they claim not to have..

CJ Link: 9836020 Xmas Voucher claims to be a £10 off voucher that expires in 6 days (but there's no voucher)

CJ Link: 9928642 WOW Deal One week spec... artwork claims to be 20% off until 5 Nov, which has clearly expired, but CJ reports that the ad doesn't expire for another 8 days.

Emailed CJ, who say it's Argos's problem.
