I don't have this device but it's a classic sign of a defective device. Since you recently purchased it, contact the vendor for a replacement or return/refund. If they refuse, contact Voopoo on their website. If no one wants to make good on it, then file a dispute with your credit card if you bought with a credit card. If bought with a debit card, call the bank up to see if you have any purchase protections and if you do file a dispute.
In the meantime, try another coil head or pod.
