I did three business with them and they overcharged twice. 1st time they refunded me. the last time they overcharged 1000 dollar and blame it is the custom's fault where my credit card was charged by them. now they still refuse to refund me. bad business. Never give them your credit card.

this is a followup.2month later i think their manager saw this comment then contacted me and refunded my money
