Not one of those worked on either mine or my mate's accounts, just the 40 last month and the 40 at the start of this month.

2664 has never worked in the entire time I've tried it (or maybe it only works once per person and I have already used it last year or whenever without noticing), and 3280 was invitation-only and didn't work either. April was a dry period for me, probably the second worst to December last year.
