Sells online stock they do not hold. Zero customer service.

Why on God's green earth does Takelot sell an online item to me, take my money, and then they do not have stock? I have committments to adhere to. And there is no one to call about this. Only a dumb-@ass chatbot that rebuffs me with irrelevant generic go-help-your-self-and-stuff-yourself answers. It's super dishonest to sell stock you do not hold!!!!!!
