Hi, MLGL, and welcome to the Community!
You may contact customer service ; please reference the correspondence you e-mailed so the status of your enquiry can be traced.
P.S. FYI, this message board is reserved for Skype Manager, a Skype business product. I can easily understand not being sure where to post your question, which is why I left it here ...
i sent a proposal to be a payment gateway for Skype Credit in Indonesia, but I need to know how can I contact someone of Skype to develop a very interesting project.
Hi, Alfin93, and welcome to the Community,
