Com Data review: Trying to get a cash advance

My company allows a $50 cash advance per day with your fueling, every time I put in for my cash advance it says declined! I can pay for my fuel but the cash advance will not go thru! This has been an ongoing issue I've had with this company, whenever I call in all I get is "well there's really nothing we can do".com data is AN ABSOLUTE JOKE! I'm an owner operator who is currently leased onto a company who uses com data, when I was using EFS I NEVER HAD THIS ISSUE! I'm talking to my company to see if I can go back and start using EFS again!
