hello,
thanks for your comments.
Yes i contacted them again, they confirmed the same address.
No i do not think there is extra character (like a space) at the end, i did it several times, tried to type it also instead of copy pasting.
The address is: 1pX8coEJV5F6Qa6t9ihXj9P9yGh99SxiM
let me know if you think of something
Maybe i'll ask the seller to re-issue a fresh one ? (i guess they can)
