I called indecisive about getting a device, but speaking to your Sales Consultant completely settled me. He was very professional, knowledgeable and patiently walked me through the process. He always responded to my voicemails and answered all my questions. After I received my merchandise, he called following up to ensure that I had received it. Customer service I would say is 5 stars. Stellar! Thanks Credit Card Processing, I will definitely recommend you.
