PinZoo sells instant prepaid wireless refill minutes, long distance phone cards, wireless phones, and accessories.
It takes days for PINZOO purchases to show up on the telephone when placed over the computer with a credit card. Sometimes there is some code that is also required to activate the account. That code is not shown unless one digs around for it as for why the phone is not working. Past minutes are not carried over to new refills either, which makes it difficult for customers who forget how much time they have left on their current PINZOO refill until their balance runs low. This is a poor way to conduct business.
