How do you claim this someone please help
You will get an email like I did yesterday with a link to a page asking you to confirm the email address is correct for where to send the voucher email.
I wasn't expecting mine for another two weeks but check your emails and even possibly your spam/junk emails.
Can you tell me, what was the name of the third party company that sent you the email?
Did your voucher actually work as mine didn't in store or online
