Unprofessional Whatsapp Agent

This will be a NAME & SHAME POST

I had some issues regarding my line speed so I decided to make use of their whatsapp service to speak to a support agent. After waiting a while to be connected I was finally connected to a Steph M. Steph M gave me some advise and asked that I switch off my router and ONT for 10 - 15 minutes while we are on the chat. So I did that but after 8 minutes I got a whatsapp saying - "I understand you may need a bit more time to get back to me. Once you're ready to continue this chat, please message us back and we'll do our best to assist you." Steph M then closed the chat.

How can you give someone advise to switch off their equipment and then close that chat while the client is doing what you asked them.

This is completely unacceptable and these agents need to be trained in customer service.
