Called and rented a bear fence, told them I would need to pick it up on a Sunday and was told no problem. Two days before my scheduled pick up they contacted me and said I had to pick it up on Saturday or Monday instead of Sunday as was agreed to. I live out of state and said I could not, so I asked them to refund my $. They said no refunds since I cancelled to late. Had to challenge the charges on my credit card to get a refund. I would rather get ate by a bear then to rent from then again.
