I am illegally asked to pay rs.1000,
Tikona customer care told me that we will consider your last usage date or termination request date whichever is later as the date up to which you would be charged for services, basis which the full & final amount will be calculated.
I made disconnection request on 4th march 2015, and my last data usage was 28th february, and my bill generation date is 7 of every month, so i want to know how come this bill is generated i have told many times to the customer care executives to please edit the bills and review the disconnection request.But i have got no replies from their side, on calling customer care, ivrs says that i will receive a call back within 48 hours.. Which never seem work out, i received calls from them, but the ivrs makes me wait and then hang up the call, the support executive never speaks.

Furthermore,
Now, i have started receiving threatening calls from unknown numbers, asking me to pay the bill or you will file a legal case in court. Generating wrong bills and threatening me to pay the bills.
Its been 15 days i am being harassed by tikona.
They ask me to pay bill in 30 minutes or they will file a legal case in delhi tees hazari court.
And one person even asked me for my debit card details,
I want to know who gave the authority to tikona or their lawyers to ask for my card details.
I want them to cross check my bill and stop creating this unnecessary nuisance and hassle. And request them to stop making these calls and update your database with the correct bill.
