Looks like it's last activity was on Thursday April 11th.
It's not unheard of for shiv and them to stop communicating for a bit, it's actually been kind of common in my experience even though I haven't gotten an e-tune from them. Dare I say it's because of all the vehicle skews they are trying to expand into, or shiv may just be busy with personal stuff? There could be a whole bunch of reasons, but yes, I would try contacting through email, phone and FB one more time during the week see if they respond.
