Leveraging my expertise in building chatbots, I took on the challenge. For nearly a month, I focused on creating a WhatsApp chatbot to address this issue. The chatbot played the role of a mediator between buyers and sellers. When a buyer proposed a visitation time, the chatbot automatically checked with the seller. If the seller wasn't available, the chatbot would propose an alternative time to the buyer. This back-and-forth continued until both parties agreed on a suitable time.
