I've been a customer for years but lately their service has gone downhill a lot. I paid for priority shipping on my last order only for them to delay the order for a few days and defeating the whole purpose of me paying priority shipping when I already had free express shipping included with my order. Now , I placed and paid for a new order on the morning of June 2nd.. As of today, June 11th , they still have not shipped out my package and the stopped replying to my emails since last Thursday when they said they were out of stock, something their website definitely did not mentioned. After 10 days I just want my refund as I had to buy locally. Now they won't ship out my order, won't reply, nor refund me. This is ridiculous. How can they still be on the market while pulling this kind of schemes ?
