Ugh... some people are difficult to help...
I bought a complete box set of ST:V on ebay, only, when it arrived, it wasn't. It was a complete box set of ST:TNG. Now, since I already have that box set, I requested a refund and return label (directly, not through ebay), guy is apologetic about wrong description, sends return label via email.
Label printed, go to the PO today on my way home from work (only time I can get there atm is Friday avo after work, covid hours an' all that) and the postie says, "nope sorry, the weight is wrong, it's a label for 800g, this weighs 1,800 grams".
Now I gotta message the guy and tell him his label is no good, and ofc being a nice guy, I'm the one feeling bad...
