Block them. They start calling when you 2 days late on your payment. My contract says 10days late they can bother me basically. I get calls on day 2 starting at 830am and get at least a dozen a day. They will get my payment. Calling me doesnt change that, and repeat calling me just pisses me off and I have them permanently blocked now.
I agree. What's even worse is after you talk to them to explain that you do intend to pay them and the payment will just be a couple days late, they STILL call. It's extremely annoying, and it would be nice if something could be done about it.
