Can’t Access My Snapchat Account After Changing Phone Number, No Codes Available

I recently changed my phone number, and now Snapchat keeps sending the verification code to my old number or asking for recovery codes that I no longer have. As a result, I’m unable to log into my account, which I’ve been using for 8-9 years. This has been incredibly frustrating, and I’m stuck without any way to regain access. I would appreciate it if Snapchat could contact me and assist with recovering my account. I’ve tried everything, but without the codes or access to my old number, I can’t resolve this on my own. Snapchat, please help me get back into my account!
