Bajaj Finserv — I paid my loan amount, but still bajaj finserv employees harassing me and blocked my card

Address:

Near Jyoti complex, naik Nagar, anantapuram

I purchased vivo y72 5g mobile through bajaj emi card on August 5th. I have to pay My first EMI of rupees 2999rs
On or before 2nd September. I paid my EMI through paytm on 2nd September 6.52 am. The mobile price is 20990rs and I paid 2999rs as EMI. in bajaj finserv App State of account it clearly showing my payment was credited and still 17991rs I have to pay. But I got a message from bajaj finserv stating that I have to pay my first EMI 3550rs added 450rs as over due price. I don't understand why I got this message. And everyday I am getting call from bajaj finserv employees and they harassing me and some were speaking without respect. Bajaj finserv were treating me as a defaulter. I paid my EMI. but still they harassing me. I even went and complain my issues to bajaj finserv employees in office but no response and not behaving properly. The biggest mistake of mine is trusting bajaj finserv and taking mobile through bajaj. Kindly please help me and solve my problem. I am attaching my payment of EMI and my bajaj account statement.
