Bankbazaar — the worthless service

I have been submitted my loan application with all the documents many times... Which is getting rejected for some reasons...in the initial stage of documentation they also give us assurity that the loan will definately wlbe approved and disbured. After receiving all the documents they is no update on the loan status for 15 to 20 days. Later if we call them they states that the loan is rejected.

This time i got a call stating for pre approved loan from idfc bank, this time also i submitted all the documents.. Later i recvd call informing that the passport size photo is blur so it can't be processed, so a advisor stated me to click a selfie with a plain background and upload it, so again i did the same thing on 2nd march. Later on 3rd again i recvd call stating that all the documents have been received and will have a visit from the banker on 6th march between 5 pm to 6pm. Which i also agreed.

Today again on 4th march i recvd call stating that the documents is incomplete... I m hospitalized still i m submitting all the required documents because m in need of the loan.. This bankbazzar is litteraly creating application and rejecting it which is also affecting my cibil.
Need justification on the same and the useless n worthless services being provided by bankbazzar
