PhonePe — Blocked phonePe account with no [protected]

Sir suddenly i saw that i am unable to open my phonepe account with number [protected]. When i called their customar support the told me that i have been blocked my account.
But i have never done this in my knowledge. Now i want to back my previous phone pe account as i use it for some important transaction.
Kindly do the needful sir.
Their opinion is not true about to block my account as per my request
