Feedback wanted on how I listed this 1980 Topps Basketball Base Set
Here is my listing: https://www.ebay.com/itm/266395216579
It sold within hours, I shipped it on Friday, somehow the guy got it today (Labor Day) via USPS. Within minutes of opening it, he messaged me and said "there's no Bird / Erving / Magic card, please advise" and opened a return case.
Thoughts? I know this is a confusing set issue, but I scanned EVERY card and gave a detailed description of what was included.
