From what I gathered, he sounds like a real shoddy business type. So VXL couldn't even get the owner to even admit he sold you this vape and help you out. He is out nothing by saying yes and helping you. Man I feel for you. If it was me, I'd gather as much info with the S/N and the date that I purchased it. Maybe there is some record with your credit/debit card of the purchase as a reference as well. Then approach VXL support with a new ticket and all the current info, and try to get it calibrated. If they simply won't fix it under any circumstances, mention it here in the forum. There are some people who tinker and know some a few repair places. If your bamboo is intact and heats up somewhat, it sounds like a re calibrate prob. The big question is how much did you pay for this and how much would it cost to set it right. I have bought both of my EVO's used and had one re-calibrated from VXL. But how does a store unit lose calibration? Sounds fishy. There is a local head shop that won't lower their price for a V-tower, even though EQ is selling for $100 less brand new. I only buy from shops that know their product and offer a warranty. Or at least tell me to register with the company after I make the purchase.
