IDFC Bank — Emi repayment

I took a flipkart later emi which was funded by idfc to flipkart, i have paid all my dues on time but my credit score has gone down drastically and the reason on the credit report was idfc loan
Gone down by 57 points

I contacted both flipkart and idfc and im not getting a proper response

Now i have another problem with idfc and amazon Pay later facilty, that too is funded by idfc,
I purchased a product on 10 sep 2021
My first due for that emi is only on oct 5 2021
But I got a notification from idfc that i missed my payment which was due on 15 sep 2021

Contacted both amazon and idfc no proper response just blaming back n forth

Now im scared that this issue will again drastically affect my credit score
