No phone number on the website... And the phone number listed for Euro Impulse on my CC charge is inactive.I know people rely on digital media/communication these days, but for something like this, I'd pick up the phone and call them. There is a much better chance that your issue will be addressed if you talk to someone on the phone. There is no excuse for not answering an email, but sometimes these places can get 100s of emails a day, and it's nearly impossible to keep up. so I can see you'd get a very delayed response if you just email them.
that said, them deleting your comment is shady af tho.
7/15 Update 3: Another email
"I am extremely sorry that it went this far. Super unprofessional on our end. I will accept the chargeback request once we get it, and I’m also going to make sure you get that shift boot. This one is on us. Hope you can forgive us.
Regards"
I can appreciate that they're admitting fault and are trying to remedy the situation. I wish things never went this far but unfortunately they did.
