How to inquire about buying a two-color ball in a bank?

When purchasing, you will be prompted to enter your mobile phone number. This is a lottery ticket with a one-time purchase price of 10 yuan, and a short message will be sent to you about the lottery results. You can enter your mobile phone number if you buy any amount, but only after 10 yuan will you send a lucky draw result message.

The lottery ticket didn't come out, probably because there was no lottery paper or other reasons, but it is estimated that it can't be taken back.
