[Resolved]  Byju's — Extra deduction of 5891/- from EMI

Online coaching for +1 and +2 for my son KARTIK MONGA was agreed for an amount of Rs.32, 500/- by Mahima madam (on behalf of Byjus). The amount was to be paid through EMIs funded by Bajaj Finserv vide loan agreement No.424 REM 82730168 indicating gross loan of Rs.38, 400/- (as against the agreed upon amount of Rs.32, 500/).
EMI of Rs.3200/- per months (for 12 months) commenced from 2nd September 2018 and concluded on 2nd September, 2019.
The Gross Loan amount was not debated upon as the loan agreement indicated the net loan as Rs.32, 509 + the interest part of Rs.5, 891/- indicated as 'INTEREST PAID BY MANUFACTURER/DEALER'.
However, instead of 32, 509/- a total amount of Rs.38, 400/- was deducted.
The matter was brought to the notice to Mahima madam and the mentor and calls were also received from Byjus office with assurance of making the refund. But the refund has not been made.
Several reminders Telephonically as well as to SUPPORT @BYJUS.COM were made (June 2020).
Ticket number of 9511033 was also provided for my grievances on 14th June 2020 but the case is still unresolved with the only wordings that it is in the purview of Higher Authorities.
Please resolve the issue and do the needful for refunding the excess deduction of 5, 891/-
