Bajaj Finserv — Advance emi updation issue!

Hi!
My name is Tushar Mathur. I'm complaining about Bajaj Finserv services.
I've made an online payment through their Experia portal on 1st May 2017 at 11:24:01 PM (according to there system time), and it has been now 20 days. My payment is not reflecting in the Experia Portal. I've made an advance payment of Rs.4778 and of Rs.1930, out of which the payment of Rs.4778 is not reflecting in the portal. Despite of sending so many emails to [protected]@bajajfinserv.in, they do not give me satisfactory answer to the question asked! All they do is send me the emi details as in, the amount of emi and the date on which it is due to be taken out from the bank account.

My transaction reference number for the payment of Rs.4778 is IHMP[protected] .
I've the screenshot as well of the payment which I made.

Bajaj Finserv people keep calling me for the due payment. Its been so many days that I've already told them that I made an advance payment, please update the systems. But no, every time I access my Expedia portal, it shows no advance payment received and whereas the advance payment of Rs.1930 is reflecting in the portal.

The payments which I'm talking about is of consumer durable loan.
My customer id is: 36791673 and the loan a/c number which I have a dispute for, is: 4010CD28630336 .

Also, there is no contact number where you can reach out to the customer service team. I've tried so many times to get in touch with any executive of their's but I couldn't get through any one them!

Please take a strict action. I'm really annoyed by the type of service they provide. No support to their customers and then they say that they have dedicated team to resolve all of the customer's problem.
