ERROR PLACING ORDER

I cannot extend my realm. I DID LITERALLY EVERYTHING. I spent on it 7 hours and nothing helped. YES, I typed all my card info CORRECTLY. YES, I TRIED to update my browser, also change it, tried to pay from another device, other cards. I DID IT. I MESSAGED TO MY CARD PROVIDER AND THEY DO NOT KNOW WHAT TO DO, BECAUSE I CAN PAY FOR EVERYTHING IN INTERNET EXCEPT YOUR MINECRAFT PRODUCTS. NOTHING HELPS, and i also read the whole your page of support, so do not send me anything from there. Just help me to pay for my realm and let me play ppppllllleeeeaaaaasssseeee.......
