I would recommend writing a few examples of the various inputs and responses that you want your bot to use. This will help ensure that it responds correctly.
- - I am having an issue in windows - Okay, let me help you with an issue - - I have an issue in windows - Okay, let me help you with an issue - - I got issues in windows - Okay, let me help you with an issue
When the chat bot selects a response, it will try to choose a response based on how closely it matches the input. The words "having" and "have" are very similar so this will often result in the correct response being returned. Inputs that are highly different from the trained responses may result in unexpected responses.
