Is goggles4u.com Safe?

Wel, I ordered two pairs of glasses and paid the extra to receive within 10-12 days, I called on day 10 and was told they are in "production" and they are unusually busy but they should be shipped within 24-48 hrs, and they refunded me the extra $4 for extra shipping, contacted on the 12th day and the website indicated they were in processing and I asked status and was told I should receive an email within 10-12 days advising when they will be shipped then I was told it was a "computer glitch" and they were still in production. So I don't know about the quality of the glasses but you can't trust what they tell you and they can't tell you where your glasses are in the whole process. And as I questioned them on the delay they threatened to cancel their order against my wishes because I desperately need new glasses and have already waited almost two weeks when I thought I would have them by now. I was told they didn't cancel the order but how can I believe anything they say and they were very indifferent about the fact that they made claims they were unable to keep, they were indifferent to the amount of time it was taking and just basically indifferent about my order as a whole, so buyer beware !!!!!!!!!!!!!
