Nobody can check anything for you. VAC bans are permanent.

I think you guys you ban my account for my old phone number. Can you please check and delete the ban from my account?

after 2313 days and this is the first and only thread you made and you asking to be unbanned. Bans are permanent and cannot be appealed. If the ban was incorrect then it would have been removed anywhere between couple hours to maybe a month or two after you got the ban, definitely not after 2313 days. But seeing this is the only thread you made, so it raises the big question of "how much did you pay to buy this account?", which is against steam TOS

Can I appeal my VAC ban?
No. VAC bans cannot be appealed. If a VAC ban is issued incorrectly it will be automatically removed after investigation, but Steam Support does not manually remove VAC bans applied to accounts for any reason.

I was not using my account when it was VAC banned. Can the ban be removed?
No. Any bans added to an account will remain regardless of who was using the account at the time the infraction occurred. Ultimately, the use and security of your Steam account are your responsibility.

While we understand this can be frustrating, we must maintain a zero tolerance policy for cheating to foster a fair game that all players will enjoy.

How do VAC bans relate to phone numbers?
VAC bans are applied to all accounts sharing a phone number at the time of the infraction. For this (and many other) reasons we do not recommend sharing your phone number or using another user's phone number on your Steam account. Accounts sharing the phone number that do not own the game the VAC ban is for will still receive a VAC ban and will not be able to purchase the game moving forward.

There are no restrictions placed on phone numbers that were on an account when the account was VAC banned; phone numbers can immediately be used on new accounts.

Note: This feature is not enabled for all games and is used at the discretion of the developer.

Thats a new one.
