Pubg Mobile — deduction of original uc and recovery

Address:

Hoshiarpur, Punjab

My game name is fur¥8 and character id is [protected].
I purchased uc in pubg mobile season 4.
The uc was around 660+ uc. And i also purchased the elite royal pass.
I recovered my uc by completing the missions.
When the trick of 8100uc comes, the google data roll back update came which deducted my whole uc to zero with my royal elite pass.
They have taken all from me. I don't want 8100uc which was a bug issue but i need my original uc back. I have written a number of mails and complaints with payment proof but nothing is resolved.

And now i purchased royal pass and prime plus membership again.

Please recover my old uc asap.
My friend has same issue but it was resolved but not mine.

I also attached payment proof.
