Nevr buy their certificates/coupons. They never work. Just a waste of money. When you ask for refund, they respond very late, name sake phone number, no one asnwers back.
They give excuses to refund the money. For my order numbers, they are making it up the price and refunding 40% of the money. When i tried to give the proof by logging in to the account, they wiped all the certificates i bought. Please dont do business with these guys.Scammers.
