CYCYHEATHeated Hat - Men and Women Neck Warmer Scarf & Heating Hats Set, 4000mAh Battery Pack, 3 Temperature Control

I thought this hat and neck heater came as a set..Does it not? I only received the neck warmer and not the hat. The whole reason I bought it was because my husband does dialysis 3 times a week and I thought these items would be helpful in keeping him warm. I don't want to return the neck warmer but would like to receive the hat also if it is a "set"
