I once used ebay for ordering 18650 battries for my mod by mistake it was order another brand battery but it was same but the brand was different so cancelled the order the cancellation report was sent but the authority to cancel the order is given to seller so the customer has to beg for it to the seller and the fun part is seller doesnt ansers the phones messeges and email and dispatched the order the and when that order came it was not properly packed and the worst part it was not 18650 battry size it was a fake battery althogh it was returned
