No customer service number. It's been a month since I requested assistance via email to zero response (outside of that they received my request). The cards have been unable to use since May 2018. It's now July and still NO RESOLUTION! I would recommend NOT BUYING FROM THEM. It seems like they take your money and do not give the recipient the option of ever using the card and they just KEEP YOUR MONEY. Not happy with their service. I called their mobile/website support # of (877) 758-6242. They stated for months that they would send an email and that I needed to speak with "customer service instead of "customer support." They could not/would not give me a # to customer service and stated that they are not provided with phone #'s. What!!??
