Didn't know you had to claim for reward card will follow link, what about tech gift.
It depends on what date you placed your order. Here is a post from a moderator to another user which may give you some idea of the timescales.
Did you place your order within those dates?
Hi @plellow welcome to the community and thanks for posting, the voucher code for the May choices tech offer is sent after you're broadband has been active for 30 days so you'll be contacted in early July with the details to claim your gift.
I've fed back the wording of the email to the gift team.
