I think you are a little greedy kid to play in a big garden where the kids not allowed to enter. I hope you are older than 18. Because you are smoking.
In fact, it was only a small difference in details. The pictures were showing an eye-drops lattice but we instead had made another kind of lattice. Anyway, you were right if you didn't like it. I offered you that I could make a new pipe with the same lattice you want otherwise you could return the pipe to claim a refund. You didn't accept to get a replacement and returned the pipe which is fair enough. As soon as I have received the returning pipe, I refunded in full as promised (pipe price and shipping cost). Right here, I have to stress that I made the refund process, NOT your card company. Also, I never intended and promised to anyone to refund any returning shipping cost if the customer likes to return the pipe. Everything has been done correctly and ethically according to my business rules.
