Cold and unhelpful customer service
USPS misdelivered my package on November 28 and was unable to recover it. It was a small order, so I expected Dynavap to quickly help me out. 10 emails later and after providing documentation from USPS that my order was lost, I finally received a canned "sorry for the inconvenience" email. This was on December 9. The only offered solution was for me to pay shipping for a replacement order since I didn't purchase their "shipping insurance." At no point did anyone seem to actually care that a customer paid for products they didn't receive. The support agent was short and unhelpful. Love the products but won't be supporting this company again.
