I'll never do business with this company again.
Zero customer service = negative 4 stars
PerfumeUSA, shipped from Canada = no stars
Actually having the Einsten Quantum = one star
After the website glitched and wouldn't let me enter my correct shipping address, I reached out to the website help like twice, left a voicemail on the number listed twice, emailed to the address within Paypal twice, and lastly rang and left 2 voicemails to the different number listed on the Paypal receipt.
I never would have received my order if FedEx hadn't allowed me to reroute the package to a mailing center.
