I’m doing a python ticket bot, but when I try to execute any command, they won’t work at all, and it would only send a console message saying

ERROR discord.ext.commands.bot Ignoring exception in command None
discord.ext.commands.errors.CommandNotFound: Command “ticket” is not found

import discord
from discord.ext import commands
from utils.responses import get_response, load_faq
import sqlite3

conn = sqlite3.connect('user.db')
cur = conn.cursor()

cur.execute("""CREATE TABLE IF NOT EXISTS ticket 
           (id INTEGER PRIMARY KEY AUTOINCREMENT, discord_name TEXT, discord_id INTEGER, ticket_created TIMESTAMP DEFAULT CURRENT_TIMESTAMP)""")
conn.commit()

class TicketCog(commands.Cog):

    def __init__(self, bot):
        self.bot = bot

    @commands.command()

        conn.close()

            await ctx.channel.send('Por favor califica el soporte recibido:n⭐⭐⭐⭐⭐')

    @commands.Cog.listener()
    async def on_message(self, message):

            return

        if "ticket" in message.channel.name:

            response = get_response(user_message)

        await self.bot.process_commands(message)

    async def setup(bot):
     await bot.add_cog(TicketCog(bot))

I just want to solve this problem
