HSBC credit card harassment for Rs.100 that I have not used

Dear Sir/Madam,

I have been getting HSBC credit card company's letter to pay Rs.100, which I have not used. In December, I believe this was sorted out through email with their company representative. I have a copy of these emails. Now since the 20 days I have 2 physical letter asking me to pay due. I have not used their card for more than 2 months now. Please let me know the next process.

Thanks,

Arun
