Talk to @botfather and disable the privacy mode.

Sequence within a BotFather chat:
You: /setprivacy
BotFather: Choose a bot to change group messages settings.
You: @your_name_bot
BotFather: 'Enable' - your bot will only receive messages that either start with the '/' symbol or mention the bot by username.
'Disable' - your bot will receive all messages that people send to groups.
Current status is: ENABLED
You: Disable
BotFather: Success! The new status is: DISABLED. /help

By default A Bot will receive only messages addressed to it by any user directly via posting by /command@YourBot any message you send.
After that it vill be available via getUpdates API call.
In browser it will be:
https://api.telegram.org/botToken/getupdates
Find the related message in output JSON and grab chatId. It will allow you to answer back with:
