Complaint Review: Walmart Green Dot Mastercard

I rented a vehicle using my Walmart money card. The rental company sent greendot the release for the preauthorazation funds over a month ago. I have contacted greendot 8 times after the 6 I was told that I needed to contact the rental company and have them send another release, which they did. In fact they sent the release 3 times. then Greendot tells them they need it in a different type of format. when the rental company ask if they could fax it to them they said NO, it could only be sent as an email, which they had already sent it 3 times.

Greendot said it could take up to 90 days for the funds to be revesed to my card. at that time the rental company advised me that somewhere in the greendot system is making money of the intrest of that money, because they release any hold on funds after 5 days. The repersentative at Green dot seemed to be very angry at that time.

I want the 460 dollars that they owe me and I promise never to use that company again nor tell anyone else to use them... such ashame for walmart
