Claiming credit card dues after returning double the amount

Hi,

I have a credit card of 30k limit. I used it fully and paid them back almost 40k extra. I have receipts for 65000 or more.

They presented the cheque in police and filed a case against me but I paid them more than their actual amount. So now what type of punishment they can give me?

The cheque amount was 100k. I want to ask you, their limit was 30k but they presented the cheque with 100k.

Isn't it illegal? And what is the procedure to get rid of this tension?

I shall be thankful to you

Best regards
