I am looking into to do legit business and provide quality service. Both things require money and time spendings. In return for my services I do not expect you pay me time, but I expect you pay me money.
That could happen because of failure in payment processing or because of you may have missed something. Please describe your situation to support service and it will resolve the issue:
Send @username or numeric Telegram ID of a person to the bot. The bot will return you a list of groups which this person is member of.
Also you can forward a message from that person to the bot. The forwarding method does not always work because a person might configure Telegram to not allow other people and services to extract person's ID from the message which he/she has written.
You can see up to 1000 groups for any person. Bot show upt to 1000 groups even it know more than 1000 groups about that person.
