AAPE purchase error and still haven't recieved Halo skins + 30 days of boost

I’ve been keeping up to date with the coalition twitter and I followed as they instructed to hard reset my console but when I did I still haven’t got anything, Also is anyone else having problems purchasing the AAPE skin set from the shop? When I try to buy the set it gives me an error code preventing me from buying when I have almost $45 on xbox giftcard left.
