No response from support after 13 days

I have created a ticket inquiring the acquisition of a certain username whose current possessor does not appear to make any use of whatsoever. However, 13 days have passed since then and I am yet to receive a response from GitHub. I do not intend to be pushy, nor do I demand any sort of immediate answer, I just want to know if this time is reasonable, and if possible, have some estimation pertinent to how long will it take for I to hear from support.

Thanks in advance for taking your time to respond to me,
Breno Santos.
