Contact email for support and/or combine licenses

CCleaner for Windows
1

I accidentally bought 2 licenses, want to combine into one.
Q’s:

  1. How do I do this?
  2. How do I contact support by email so they can help me do this? (I haven’t been able to figure out either.) Thanks in advance.

send from your registered account if at all possible. Please be patient as support can run slow these days, atempt not to send multiple email as this may reset your automatic queue to be helped.

i am a moderator only and cannot help beyond that (they are as slow for me as for you)
