Payments usually need 2-3 WORK DAYS to get through.
The 20th of this month was a Thursday and because Pentecost and Pentecost Monday are banking holidays, you can expect your money to show up on your account on the 25th or the 26th.
The way CGT displays processed payments are not very "user friendly" and adds to the confusion. They should place some sticky notes somewhere for clarification.
I have had this issue several times and they turned out to be "false alarms".
Still...the reason why they show misleading caption, knowing that payments are "delicate matters" for sellers is beyond me...
