Tikona — Broadband internet

I have taken a new connecting paying advance of 2250 rupes, I never used it properly but waited in patience that tikona service will improve but even that period I have paid 3 bills in time, as there was no impovement in service I requested for cancellation, after several emails and calls they cancelled the connection but still I am getting bills and some one is calling and threatening me to put court case and they are asking to pay 800/- rupes and asking me to come to delhi . I donot understand why should I go to delhi for paying 800/- .
I got call from this number [protected].

My Billing Account Number[protected].

I have made very big mistake, I[censored] Tikona need money let me know, I will pay but please donot send goons and threathing calls for 800/- . I did not use more than 1 GB till now and would have paid nothing less than 5000 and additionally I am getting such a calls .
