I was using Tikona since last 2 years and had a worst experience . There is frequent disconnection. Very bad speed. Also when I started for disconnection then real drama started. They sent full bills. inspite I requested disconnection ad didnt use net for complete month. I simply say in delhi best is MTNL or airtel. Dont go for tikona. they are bunch of thiefs. Mt customer id was 1109025542.
Also when u contact J Nair they these idiots dont responce. It seems tikona team has done some specialization in fraud and idiotic behaviour
