In 2018 one party had supplied the goods to second party. and now in 2020,march second party is saying to one party that your credit is not reflecting in my GSTR 2A so I will give u debit note for tax amount which is high amount.

Actually the first party had filed it's gstr 1 with wrong party name in July 2018.

is there any way out for this?
