Tikona — Cheating case/ worst service/ harassment

Hi Sir My tikkona user id is [protected]. I installed their service months ago by giving two months advance payment. But there was not a single day this internet worked perfectly. I put about 7-8 complaints per month and was given same response that server issue, tower issue or hub issue.. Later I asked for refund of my money, they asked some time and promised me issue will be fixed. After two months I told them to disconnect my connection but I get a mail that we will fix issue or give a waiver. For one day they make it fixed and resolved complaint, and from next day same issues were there. They started sending me next month bills too while i have told them to disconnect. Now they are calling me each day by recalling legal notices and rest. I request them to check my complains logs before harassing me.
