Paid for req packs denied

I have noticed an issue with purchasing req packs. I tried when the mechanized pack came out to buy one and it said “try a different offer” “sorry your not eligible for this one” disappointed but figured ok whatever no big deal mis be a pRobles with the new pack. Now about a month later I’m trying to buy a pack of gold req packs and amd getting the exact same message as before. Iv tried multiple times and same result. So clearly I’m having a real problem. How can this be fixed? I mean its you guys loosing the money I want to spend on you, so help me out asap please before I lose my urge to pay XD
