www.kabbage.com / Strange rep, who asked for money all the time

We took the small loan from the company www.kabbage.com. Everything was ok and we signed the agreement with them. Unfortunately, these jerks started to ask for money back too early. The rep started to call us and asked for money. We told him that we would return the loan, but on the estimated day, which was indicated in the agreement. The rep agreed, but on the next day called again. WTF? I wonder if there are other people, who had the same experience. Can you provide any good piece of advice?
