Bajaj Finserv — Loan account number P406PGD3878618

I have applied for Balance Transfer in Bajaj finance on 8th Feb 2022. The executive has done all the process and handed over the cheques to me on 15th Feb 2022 of dated 11th Feb 2022. When I submitted that cheques to respective banks for foreclosure, then I came to know that the amount which I got from Bajaj Finance is less than the foreclosure amount. Then i contacted to Bajaj Finance Executive and told about then he assures me to re issue the correct amount cheques within 3 days on 17th Feb 2022 but till date he has not reissue the cheques to me but EMI of Rs. 17318/- amd Mandate Fail Charges of rs. 295/- on 03rd feb 2022. Since your executive assuring me of refund but my money is not refunded me yet. How it is possible with such a big company.I dont know whether it is systems fault or Executive.
Kindly look into this matter and resolve my issue as earliest.
