Not impressed w/customer service. When making an order, you cannot add/change quantity, until after you click "add to cart", which is confusing. On 1/5, I called the customer service number, but they were busy, so I put in a request for them to call back (but still remain in line in the queue). Never heard back from them. So I emailed them telling them I needed to add another pair of the glasses to my order, never heard anything from them. I finally received a reply, stating they couldn't make any changes to the order because it had already been shipped out. While I appreciate the fast shipping, I was not able to get a second pair of glasses as the same price. I attempted to reorder, but I did not get the discount I had received in the first order.
