I used EZ contacts due to the good pricing. I never received a confirmation email regarding my order. I never received an email stating my order shipped. when my contact arrived, they arrived in good condition but no packing list. I have tried to use online chat to receive an invoice or order confirmation to submit to insurance but there is no one manning online chat. Instead, they send you an email. I have asked three times for a receipt. They get back to me timely and say they are sending it as its own email. It never comes. I have been told to check my spam, but nothing. There is an issue on their end but this is ridiculous. DO NOT order from this company. I had much better luck with ContractLensKing in the past, but they were more expensive. This is a disaster.
