I am pretty disappointed with Pure Vapes customer service. I ordered over 40 3ml samples from them, and received them with no invoice. After checking my order, I realized that 2 bottles were missing. There is no contact information on their site so I sent them TWO emails through the site and still no response. I sent the second email on Saturday and the first one was maybe 2-3 days before that. Sorry for the rant/being off topic. It's only $3 but the point is, I want what I paid for! And it sucks not getting a reply.
