Welcome to the chatbot/AI age where nobody knows how a telephone is working

I ordered and paid for a product including delivery, only to realize there is a pick up point near me. No way to cancel the delivery and get a credit. No telephone number to phone. Only a chatbot that refer you to a website. Money out of my account, but showing awaiting payment. No telephone number to speak to someone. I will never order from an electronic chatbot company again. Why can one not phone someone to speak to??
