Our company (in the US) purchased the $2300 netweaver sdn development subscription but we haven't received any boxed software, and have received no communications from sap. Who is the best contact to resolve this issue? We have emailed email@example.com with no response. Calling up SAP and speaking with several different departments, no-one seems to be able to solve this issue. No one has a contact phone to speak with a person. I've probably sent out a total of 25 emails and have made numerous phone calls to SAP with no positive result. Thanks for your assistance.
