I stopped playing Pubg Mobile a while ago at the same time I changed my phone number, I have photos inside my account and also one that a friend of mine had, In the account, the only verification I placed was the phone number, but I no longer have access to that number. It is linked to Facebook but it does not let me access it because of the verification, I tried to fill out the form but they just rejected my request knowing that it is my facebook and an old ex phone number. UID: 567455725 It's the same account with a different name when I stopped playing, I hope someone from support can really help me, since the form really only rejected my request.
