We rented a vehicle out of the Brainerd , MN airport. The pick up time was on my paperwork but when I arrived the Alamo kiosk was dark and no one was in attendance. I called the local office and was told someone would be right there. I waited a good 50 minutes. We spent time filling out paperwork and then it came time to pay. My debit card was refused and I was told they would only accept a credit card. I had none. I had to drive 40 miles back home to get a credit card and then drive back to the airport. On my way back an agent called to tell me they had the-evaluated the situation and I would be allowed to use a debit card. At this point I had already driven back home. And wasted 1 1/2 hours drive time. I did finally get our vehicle but it had only 1/2 tank of gas??? We had to stop and gas up enroute to our destination. The only redeeming news was when we shared our exasperation with a fellow from Enterprise at the MSP airport, he credited us with $40 upon the return of our car. Very nice guy!! But that should have been done at the Brainerd office.
