My company booked and did a load with broker Erica. We booked for next day delivery from CA to AZ. But when my driver reached at the receiver they said you don't have any appointment for today. but we can arrange for tommorow. So I called broker and we decided on layover for $250. After delivering next day we asked for that money but she refused to pay us and she started blaming on us. I tried to reach her so many times for it but she said she is not going to pay us.
I will tell everyone not to work with them specially with this lady Erica. They should be respectful and also pay us what we decided on.
