Dead Robot

I’m irritated that my LEGO Mindstorms Education Core Set did not include a charging cable. The Education Core Set from LEGO does include a charging cable, but the third-party seller on Amazon that I bought my kit from is selling the “Education Core Set” without the charging cable, for a higher price than LEGO, and selling the charging cable separately. And, Amazon has the seller listed as “LEGO.”😡 I didn’t realize this when I ordered my kit. (Why would I buy a robot with no way to charge it?!) On Amazon, in the questions, someone asked if this was the SAME set as the one on the LEGO site, and the response was “yes.” It’s not. My robot is dead, and I’m not happy.
