Reinhard,
Good day, I hope you are well. In order to provide you with a thorough response to this inquiry we will need to collect some information from you. Can you email me directly your contact information so the GTAC can open a case for you or please contact the GTAC at your convenience to open a case? If you do open a case directly, and do not mind spending the time, please also email me the case number.
Thank you for your time
Brian Townsend
