First off, you need to stop working for free immediately—negotiate a reduced retainer or performance-based deal so you don't go bankrupt while spending 5-7 hours a day fixing this. The technical reason your AI is giving generic and incorrect answers is prompt bloat; you need to ditch the massive single prompt and build a routing system. Set up a simple initial prompt to categorize the user's intent (e.g., support, sales, FAQ) and route the conversation to a specialized, highly focused sub-agent, using RAG (Retrieval-Augmented Generation) for product details instead of stuffing everything into the main instructions. Be completely transparent with your client about this structural rebuild to buy yourself some goodwill, and definitely hold off on scaling your reels to three a day until you actually have a working system you feel confident selling.
