Bad Service. Blaming it on their AI.

Ordered online a complete Ultra Zap kit. On request the Help assistant on line showed me a numbered list of what is included. Based on that I ordered two kits. On arrival half of this list was missing. When I phoned to correct the order I was told that AI made a mistake and that they are not responsible if their AI made a mistake! Then to top it all up the phone was just put down!
