My Snapchat Account Was Permanently Banned – Need Last Contact’s Username

My Snapchat account was permanently closed for no reason, and I don’t understand why. I had my account linked to both my email and phone number, yet Snapchat suddenly disabled it without any explanation.

Now, I need to find the username of the last person I chatted with, but since I can’t log in, I have no way of retrieving it. Is there any way to recover this information?

Also, Snapchat, why are you randomly banning accounts? This is completely unfair, and I expect an immediate explanation and resolution. If you are going to permanently ban someone, at least provide a valid reason! Please help me recover my contact information!
