Don't delay if you receive a Tango Card! Their business model is betting that you will leave them the unspent (or returned) balance!

I received an email link for money from Tango as payment from GLG for a consultation, but I did not spend the funds until a few days before the Tango expiration date. Due to a shipping issue with an on-line purchase using the Tango card credit, the funds were returned/credited to the Tango Card one day after expiration. However, since the card is now expired, I do not have any access to those funds (but the return credit link apparently works fine to take the money back!) I spoke with a customer rep the day before the return of funds, and he assured me that I could get access to those funds since Tango could modify the expiration date. Since there are no fees charged by Tamgo, it's clear that its profit is made by applying strict deadline rules and by pocketing all of the unused funds - in this case it was an easy $650 for Tango!

Also, on the last evening I tried to spend the remaining $35 when it was only 10pm in California -- apparently, the deadline is eastern or central time (even though Tango is a west coast company!)

It will be interesting to see if Tango makes any accommodation for the funds that were returned/credited back to my Tango account...
