Anything above 30% of available limit (For Example if limit is 1 lac and you spend more than 30k in a month), it will negatively impacts your cibil as you will be seen as credit hungry. And here you are trying to utilised 100%of that limit, why?
Now pay overcharge, pay amount such that total amount becomes less than 30% of limit.
Next time don’t go past 30%of limit unless it’s absolutely urgent.
