Hi,
Thanks for posting your concern.
So that I can discuss your issue with the rest of the team, could you please help me with your customer ID and the complete SOAP request and response logs together with the error message? If you haven't enable the SOAP logging, you may refer to 'readme' section of the corresponding client library that you are using (please see this link for client libraries).
Regards,
