MoneyTap — Made the payment but not reflecting

Address:

Pune

I have taken a loan of 45000 in 2019. I have paid all the payments on time. In the month of December 2020 the payment for 1099 was due. I had maintained the balance in my bank account. They took a payment of 929.83 on 7 December 2020. They haven't updated this payment and keep asking me for the payment. They have sent my account to collection agency. Collection agency guys are harrassing me for this. Please help me.
