Orders incomplete

I ordered the recovery device, phone connection cord, and adapter and one other thing I don't remember. I haven't received any of my order, I was sent a message that 1 item wasn't available anymore,so I waited another week and they seem to have an issue with my whole order. It was all paid for. I finally figured that since they are unable to have any of my order available I decided to cancel my entire order and requested a full refund. I was sent a receipt with copy of my full refund minus about 30.00. They want to give me 76.00 of my 110.00 dollars back. So I'm getting charged 30.00 approximately for waiting for over a month to receive nothing but get a refund. I'm thinking that that's a company too work for because you can get paid for doing nothing. Definitely not my idea of a good company policy. My suggestion to correct this is before you advertise having items for sale that you know you can complete the orders that come in and if you can't accomplish that then don't offer it. I also think that if you accept money and don't produce what was ordered refund the total amount that the company received from the customer.
