Consumer Redressal

I have taken a Yearly plan of "You Broadband" with full payment from last month i am facing multiple issue like Disconnection, Speed and entire Outage problem i have raise issue with the You Broadband Customer Care on that they informed me that they have created a ticket and the issue will be sorted out on consistent follow up i got to know that there 'Technical Person" will visit and look in the issue with in 24 hours time, now almost 4 days have pass and no body has shown up today i again called the Customer Care and requested to refund my un-used amount so that i can hunt for some local ISP who is at least taking proper care of his customer on which they replayed its not possible "they have no Refund policy" that means they just know to take money from the customer ,neglect the customer give worse service and when ask will say "no Refund Policy"
