Any tips for having a "bait" line for tech support scammers?

Hello all.

I recently got back into scambaiting and was using new methods such as the grannie recipe method and spelling common websites wrong. Turns out not to my surprise these were jackpots and had tons of numbers. I called these numbers and went into my usual bait tactics - saying I have a slow computer, popups, and getting a phone call. Whenever I said these to scammers they just say "Have a good day thanks for calling." Then they hang up. What do you guys say to tech support scammers as a "bait" line? Thanks for the help, JM.
