Tikona — Connection surrender

Address:

Chennai, Tamil Nadu

My tikona account number - [protected].After severe frustration with the service, I've sent mail to customer support 10 days before for surrendering my connection. Since I'm working for a banking client I clearly told customer support that I cannot pick calls and asked to consider my mail as a personal acknowledgment for disconnecting connection. I don't understand why these people are not considering my surrender request. I've stopped using the service 10 days before. And I've received bill for this month. Why should I pay for something that I've not used.
