[2020] [Ubisoft Store]i can't buy anything on the uplay six siege

i tried for almost 5 days to buy, the customer support dude said to wait 48h, i waited and nothing happend. so i went to uplay store in my browser to try and buy them with my paypal, and it says we were unable to process your payment, try another payment method, ok i tried to buy with my card, same story. i am literally blocked from making any purchase on the uplay store
