fraud by tikona please beware

i took internet connection from tikona broadband in delhi but after using for 5 months i made a request for disconnection the docket no. of which is 1-3560583992, but after making numerous calls and pursuing nobody came to disconnect the connection. After making efforts tikona executives told me that we had stopped your rental and you have to pay 2300 outstanding bill, i immediately paid the bill. after 2 months when i was casually checking i saw tikona generated another 3700 bill for the data which i never used. the ip addresses were random and does not belong to me. i again contacted the tikona and told them to suspend account if someone is illegally using the internet, to my utter surprise their executive named atul told me that even if someone is using illegally from your account you have to pay the bill and i cant suspend your account , i pursued their executives for suspension the docket no. of which is 1-3902988715 but they are not suspending the account and showing random usage from various illegal ip addresses which does not belong to me (attached is the excel file of illegal usage summary.)
please take necessary actions against this fraud company and i request every consumer to never take connection from tikona as this is a fraud company and making fool out of customers is the forte.
