Tikona — Inethical behaviour and unauthorized billing

Address:

400078

Had tikona plan for 1 year.
There connection was already so bad that i had decided that i'm not going to extend it anymore. And they have never came it to resolve any sort of problems.
They extended my plan without even cross checking with me. No mail no phone call just extended the plan.
The person who had given me the connection is probably not working with them anymore.
Harassing me since past 4 months. Even after number of mails and calls they have not pull down the machine.
And now they are asking me to pay rs. 740/- i've personally unplugged the machine and asked them to take it down or come and take it i've mailed them 2-3. Please check the attach image.
Their employees call and talk in very rudely.
I got a call form theie call centre and as usual explaining her everthing, i said i'm not gonna pay and the girl on the other end was like "go go".
Everytime the keep on calling and everytime i've said i'm not gonna pay as it was extended without my knowledge.
