coin gifting bugs!

HI guys i hope sb can help me with my problem but i tried pretty much everything and i think its a general issue.
I have the problem that i cant gift coins to an other cahracter ( account) . I ofc waited 72 and hours and as i tried to gift coins from my twinks account to my main account there came a message that the receivers character does not exist. I wondered if i maybe did sth wrong but i tried even sending coins to other random peoples in game but nothing worked. I really hope sb can help me and this problem gets fixed!
Greetings gillo
