I have been attempting to contact support for several weeks now. I just need a license reset due to indexing too much data and to get a quote for increasing our current license to index more data. I've tried calling every day but no answer, and submitting a case page keeps not going through whenever I hit submit. How am I supposed to get support when nothing works?
Licensing is not a matter for Support. Contact your account team or Splunk Sales.
I've been calling them for weeks with no answer
