Cash Net USA

Does anyone have the corporate number for Cash Net USA? I just wanted to set up an extended payment plan of 6 payments, and the collections department on the phone will only let me extend it to 4 payments. I have been a great customer, never defaulted, and am just looking for these two extra payments. I thought perhaps if I try going higher, I might get a better result. Otherwise, I think I will have to default on the 15th and see what happens. Thanks!
