How to send different messages on consecutive unknown visitor messages?

Bot should by the first unknown message the bot answers :

Hm...could you please explain me what you exactly need in simpler words?`

By the second unknown message the bot answers :

May you were a little bit more specific ? I really want to help you.

By the third unknown message the bot answers

Sorry, it seems I am not experienced enough to advice you accordingly. But, i suggest you sending an E-mail to ..., so my collegues can answer to you tomorrow. Thank you for effort! Till next time!

Implementation

For that we need to track how many times bot has failed to detect visitor intent.

We will need for simplest scenario 6 triggers

• Default - default trigger
• Car information - trigger which is found by default
• Unknown 1 - trigger with checked flag Default for unknown message
• Unknown 2 - Trigger which is executed second time for unknown message
• Unknown 3 - Trigger which is executed third time for unknown message

Default

Just a default trigger

Car information

This trigger is executed if user enters car as a keyword. This trigger also has send block which sends a trigger which resets our unknown counter.

Unknown 1

• This message is send first time on unknown visitor message.
• It has checked Default for unknown message
• First part of response is required if it's not a first time visitor sends something unknown. If that happens we execute Unknown 2 trigger.

Unknown 2

• This message is send second time on unknown visitor message.
• First part of response is required if it's second time visitor sends something unknown. Number 3 is NOT a typo. If that happens we execute Unknown 3 trigger.

Unknown 3

• This message is send third time on unknown visitor message.
• We also send a block to reset repeat counter.

Reset counter

• It resets our repeat counter so next time we will start from Unknown 1 again.
