Best Financial Services in Phoenix AZ

I am a small business that provided a service for this company. I am a mobile forklift company and I came a performed services asked of me. I invoices said services and waited for payment. The invoice ran past due 2 days and when I called the company refused to pay the invoice siting they assumed the service was free. This was never discussed nor is it a thing any company in my field provides. I was then told basically too bad there is nothing we can do for you. I would highly recommend getting paid in advance if you are planing on doing business with this company. Chris and Craig are the two in charge of taking advantage of companies like mine.
