In the attached screenshot, after answering my query, the bot is going back to the beginning of the message and triggering the first message again. How can i stop this? Because, i wanted to ask few more questions related to the service that i choose. (If i choose Single/Multiple choice card- it'll cause for the uncomfort to the user.) Hence, without using the card, i wanted my bot to serve multiple questions.

Hi, have you tried to connect the desired card with the 'End' node?

If you want your bot to answer multiple questions without prompting your user for a new question each time, use the "Wait for user input card" in subsequent nodes

Thank you Robert, for your reply. I tried the "Wait for user input" and attached the screenshot. But i got couple of doubts here: 1) One card of "Wait for user input" serves only for 1 time (i.e. only 1 question)? If so, we don't know how many questions would be asked by customer before he/she moves forward. So, how can we decide the no. of "Wait for user input" cards to be added? 2) If the customer is waiting without asking any further questions, bot should trigger a "Single choice" (like 'Do you have any further questions'?) question after waiting for sometime (For ex: 2mins). Where and How can i control this time?

you can adjust your bot's "Timeout" with the timeout workflow
