Bajaj Electronics — EMI pay issue of every month

Address:

madhapur branch

Respected sir,

I had purchase Electronics(LG LED TV - 22, 201/-price) from madhapur branch last year 3rd august 2020.
I have paid 7404/- down pament at branch.

I got 12 months installments started from september nd 2020, first instalment 1387/- on september,

and evrymoth i have paing 1505/- till now all the installments,
1505/- rupees are being cut every month,
More cuts are being imposed than expected.I want my extra paid money to be put back into my account
At all the money I have to pay every month is only 1234/-.
but now I didn't the installments completed msg or Email.

I am worrying that they will deduct extra instalments from my bank account.
