"The worst calling card online sellers ever! After placing an order, there was a receipt at the end with an invoice number, but I've never received any confirmation email nor PIN. After waiting for a few hours for a PIN, I decided to sent them an email to ask about the process as I've never bought online phone cards and had to wait this long. Right now I've sent them 3 emails and there is no reply. The 24/7 customer service hotline they claimed they have doesn't exist. I just hope they don't charge my credit card a week later as I do not want to give this company my business and I like to warm those out there to be careful buying from thaidial.net"
