Direct Knife Sales review: No/slow delivery of product 4

As per their shipping policy: "most orders are sent out within 24-72 hours of payment. All orders take about a week to get".

I think the lack of a physical address should have been a clue.

We ordered 2 orders of knives on August 3rd. On August 6th we received an email 'order completed'. No shipping or tracking info.
On August 17th, after a few attempts to reach them - no one answers the phone during business hours, it's only a voice mail box - inquiring about our order, we were informed that they would 'check into it'.
On Monday, August 23rd we still had received no information about our orders or the orders so I left a detailed message canceling the orders (I included the order numbers in my message.) I requested a confirmation of the cancellation within 24 hours or I would file a chargeback through the credit card company.
The next day we received a shipment notification. Note we ordered on August 3rd and exactly 3 weeks later they decide to ship, without any communication with us, the customers regarding the delay from their promised 24-72 hour shipping policy.
I sent an email saying that there would be no one to accept delivery and the orders would be returned to them. If they do not issue a prompt refund, I will file a chargeback. 2 business days later and still no reply from them to that email.

Note: credit card companies are very sympathetic to the customer and it creates a bad record for the merchant to have chargebacks - enough chargebacks can cause the merchant to lose their merchant account for that credit card.
