Good afternoon,

In April last year we paid the registration fees for two participants to the Forum on tracking Detector Mechanics 2015 (held from June 15-17th).

Name of the participants: Claudio BORTOLIN and Szymon SROKA Total amount: 360 CHF Bank account: FR76 1882 9754 1604 2685 7464 026 Value date: 23.04.2015

On March 10th of this year we received a notification from our bank with the following comment: "Money refused". We are a bit surprised to receive this notification almost a year later. Furthermore I have asked one of the two participants who told me that he took part in the conference without any problem.

Would you happen to know what has happened with this payment?

Thanks in advance for your help.

Best regards,
