Cannot Access My Snapchat Account Due to Old Phone Number

I have lost access to my Snapchat account because it is linked to my old phone number, which I can no longer use. I had not yet updated my account with my new number or email, and now I am locked out.

This account is two years old and contains important information, so I need to recover it as soon as possible. Every time I try to log in, the verification code is sent to my old number, which I can’t access anymore.

Snapchat, please provide a solution so I can regain access to my account. I need to update my contact details and log in without relying on my old number. Please help me resolve this issue quickly!
