I am using Tikona since 2 months now. I had MTNL previously, it was a ok connection. Once I was at friend house in same apartment and he is using Tikona for more than a year now. I experience very good connectivity there and he was paying very less than what a pay for MTNL. As per his experience and suggestion I decided to switch to Tikona. Before opting Tikona, I reviews various websites including Mouthshut and found negative comments everywhere.
Still I went to subscribe it because I felt people tends to write negative very easily but very few will write positive and this is for all brands. And Tikona is the only isp who is replying all the reviews on Mouthshut and I found some post tagged as issue resolved. Unlike the MTNL who never answers on call, Tikona at least taking efforts to reply on reviews.
More than online reviews I believed my friends recommendation, and took Tikona. Till date it is working very stable . Also tried to connect customer care, it took time to connect, but the agent was courteous on call. Hope I will not require calling frequent them. Also my friend is getting benefits in billing for referring me.
