payment error when purchasing first license

I have tried to purchase a licence in every way and it simply won't accept my payment. I have read many posts with people having this same issue and it seems it simply is something Adobe won't fix. The only way this problem has been being solved is with direct intervention from a suppor agent, so here I am requesting to be helped in such way. I already called my bank and they said no purchase attempt has been registered and tried every card I own, so as I said, I have the same problem lots of people experience. 

I'm trying to purchase the plan shown in the picture from Mexico, my cards are also from Mexico. I'm doing everything right and I have followed every single advice I could find in these forums. Please help me with this purchase. I have a brother trying to do the same for him so he will be next to create a post like this to receive help.
