Consumer Redressal

hello I am Anirban Roy from Pune using Tikona Broadband for last 1+ year but their service is very bad, time to time net speed get slow even stop working . I pay 1000 rs /month for 2Mbps connection but most of the time I get below 1000kbps.It takes hours to finish a task which can be done in minutes with the promissory speed. In last few days it gone unbearable, in every few mins speed gone below 200 kbps,i call customer care but they give only promise but no improvement. every costumer care executive admit about their faulty tower/network but nothing happens. my pray is that they should improve their service otherwise refund my money of this current month.
