Buffalo are ****mers

This is the worst company , they lost my package and their customer service is as bad as s*** still waiting for my refund but not even as so much as an update. What I don’t understand is why TEMU and SHEIN use them. Once they do not deliver TEMU tells their customer that there is nothing they can do as if the customer chooses their own carrier. The best thing to do is not to by from TEMU and SHEIN whilst they are still using Buffalo as their carrier. Buffalo has the nerve to ask you to pay for tax again whilst they have not yet given you a refund, the logical thing was just to deliver for free on your next order provided that the tax value was the same.
