Went to use my Walmart giftcard as soon as I “unsealed” it and the card said 0 balance. Was told that this is an unusual issue and to contact a company Buyatab. When I immediately replied saying that this Buyatab company has numerous 1 star reviews of people saying they got giftcards with 0 balance and that it was a scam they emailed me back a couple of minutes later saying that the giftcard was redeemed after the sale so somebody either has access to my email or someone else used the card. I work with computers and know that my computer and email are not compromised. This is a straight up scam and BitRefill is responsible for using such an untrustworty company. I have used BitRefill and have gotten 2 legit online cards for Amazon. If my computer or email were compromised then these codes would have been used too. Again, I work with computers and am very knowledgeable about them so I know for a fact that my computer and email are not compromised.If I get my money back or a working card I will edit this review, but I can’t trust a company that uses a giftcard supplier that are known scammers.
