Consumer harassment, cheating & looting residing in Gurgaon

Hi Sir,
I have been residing in Gurgaon, & I availed the services from Tikona by paying them services charges for 90 days as advance rental from 27th Oct-16 to 25th Jan-17. After 15-20 days i faced Internet connectivity issue for almost 35-40 times till Dec-16. From 1st Jan-17 i insisted Tikona Customer care representatives to terminate the services as i am no longer interested in using their poor services. I continued to contact them till 8th Jan-17. One of their customer care representative assured me that your services will be terminated automatically after the expiry of current term, that is 25th Jan-17. He also asked me to drop a mail to appellate@tikona.in. As requested i drop a mail to appellate@tikona.in requesting the termination of my services and account as on 11th jan-17. But i do not received any confirmation mail so i again contacted to tikona customer care to address the issue. They confirmed me that your issue has been addressed and you dont need to worry. Your services will be disconnected/terminated by 25th Jan-17.

On 26th Jan-17 I received a message that a new bill has been generated against my Tikona account. To confirm this, i checked the internet connection and it was still working. I was frustrated, on that day i again contacted Tikona customer care to ask them that why services is not terminated, I said that i will not pay them a single penny nor i am going to use their services. Customer care representative said that that's its our technical fault and you don't need to worry and do not required to pay & your services is now terminated by the end of today.

I also shifted my residence from that location, and after 4 months, i received calls from their lawyers from phone no: 8510882845 & 8750098887 said me to pay Rs. 3.6k approx against due to Tikona Digital or they will file case against me. These bills were generated on 26th Jan-17 onward which i don't used.
Now they are forcing me to pay. This is a clear case of consumer harassment, cheating & looting. How can they raise bill against me despite of my several requests to cancel my subscription & the services i don't used?

I request you to kindly look into this matter.

My Tikona Userid was: 1119695949

Update as on 18th June-17

I am loosing my cool. I have several times requested Tikona Customer Support executives to terminate their services because i am very frustrated on the kind/quality of services they are providing me. I asked them that i want no other resolution but to terminate their services. Despite of my several requests, they didn't terminated their services & raised bills on me. Today i had a conversation with one of their representative from mobile number: 022-41257373 & 8291974497 & they confirmed me that we had sent you a mail against your suspension request stating that technical problem has been resolved and you can now use our services. I asked them, on which mail did you sent me the mail? He said that mail was sent to sumankumar@outlook.com, which is different mail than my current email, i shared to one of their installation person. Mail that i shared to them was: sumankumaar@outlook.com. They were sending me mails on incorrect email. I requested their customer care executive over telephone and asked them to terminate your services & i do not want any further resolution, I just want you to stop your services.

They didn't terminated their services & said that you have paid for your services till 25th Jan-17. We request you to use it till 25th Jan-17 & thereafter we will terminate your services. But on 26th Jan-17 i received a message stating a new bill against your account has been generated. 
I am loosing my cool i want to beat this idiot company owner & other customer care representatives so hard that they will bleed till their death. They had wasted my Money what i had paid them in beginning and are also wasting my time now. Mentally harassing me, which is totally unacceptable for me. I want to file a case against this idiot looter company
