CreditMantri — closure of account

Address:

Hisar, Haryana, 125001

I want to close my account on creditmantri and want them to delete all my details. I emailed them about the same but they are not closing my account and sending me emails. They said that they will close my account within 48 hours but its been more than a week and till now my account is not closed on credit mantri and even they are sending me emails about their offers. I also message them that do not email me but they are not stopping. Please solve this issue and help me in getting my account and data deeted from credit mantri because there is possibility they can misuse my data.
Thanks
