Christian Books.com has completely unethical customer service. People who pick up the phone have no respect for customers and are extremely rude. I placed 50 copies of training materials on early Monday and paid extra for two days' shipment. After the order was set, I called to confirm everything was correct, and the guaranteed shipment after two days would be Wednesday. After two days, I received an email stating that 30 copies of my order had partially shipped and the rest 20 copies will be deliver on July 4 (i. E., after three weeks.). I called and spoke to a person named Chris, a person of extreme disregard for customer service. Chris declined to return the extra payment I have made for the expedited shipment. He said the two-day expedite shipment starts when the order has shipped, NOT the date the order has been placed. I had never heard of such expedited delivery before. My order was for Sunday School teachers' training over the weekend. Chris said you could cancel the order and go elsewhere if you want. I had never had such disrespectful customer service, which was very disappointing.
