Simply by lying to them at every step. Examples:
1. Send the phone number to them to call and let them listen to pre-recorded message saying that there is no one to speak to you.
2. Say that the best way to contact us is use Live chat while live chat isn't working at all.
3. Repeatedly say on live chat that agent will be with you in 10 seconds and repeat for over half an hour.
It is all how the ID Mobile works.
