Captial Float — Capital Float Loan given but yet asking for money. and many harassment calls

Fraud agencies having very bad customer support. I have paid the emi loan after that also asking for pay. The customer support Her name is Deepa she behaving very rude and saying out of her words. This is not acceptable. I have opted for Amazon pay captial float Emi Loan option. I have done payment through phonepe but it got refunded due to sever issue. Since I was busy I didn't notice refund and didn't get any messages as well. Now they charged 800 plus as fine for my emi amount. This is not acceptable. Deepa is behaving very rudly.
