HDFC Bank — request for cancel one assist services

Dear sir/madam
I m a hdfc bank account holder before three months i applied for credit cards but till now i did not receive my credit card my credit card last four digit 5723. One assist services has been imposed on my credit card but i m not intrested in this services and your credit card executive did not asked me for this services. I called many time credit card customer care for this service but i did not received any response from your side i m very upset from your services. Rs 427 has been deducted my saving account against this services. I request to u pls stop one assist services and pls get reverse rs 427 in my saving account and pls give my credit card asap.
Thanks
