PhonePe — Phonepe miss using KYC

Address:

I have an phonepe account with [protected], i submitted a request a year back to close my account attached with above phone number but today when i go and check it still active and my KYC also there, due to this i am holding this number unnecessary from last 1 year.
And afraid of missuse of my KYC with phonepe.
