Consumer Redressal

I was using 2MBPs Tikona plan and was not getting speed. On calling sutomer care, they advised to chnage the plan to 4MBPs with additonal cost. I did the same but later speed was further reduced to around 4KBPs!!.I requested Tikona care to resolve the issue but they kept convincing with no results. Finally, I asked them to stop the service but they still kept it ON from their side. From my side, I stopped using it. After few weeks, Tikona requested to check the speed. I logged in and the speed was still a problem. After few days, they handed me a bill saying that I used the service as reflected in last login time, so I need to pay!!BUT, I logged in just to check the speed. Since then Tikona is continuously calling me to pay the bill. This is a kind of harassment and hence would like to lodge a complaint
