New AA card customers - missing cashback?

Hi fellow MSERs,

Did anyone take up an offer which I believe was advertised on this website's credit cards section around 7 months ago (Dec '16) for an AA Dual credit card, which had an offer of £50 or £55 cashback credited to your account if you spent £300 or more on it in the first 3 months of getting the card.

Basically. I took up the credit card, followed the instructions regarding the spend, & have not received the cash back credit.

I wish I'd kept a screenshot of the application page, because AA credit cards now have no record of my application using that offer.

If you took up the offer, & have had the cashback, or indeed experienced difficulties, it would be great to hear from you, as I think the AA are trying to swerve out of this one!

Thanks in advance!
