Nextra broadband company has not refunded my security amount rs 1500 after disconnection of services, i had mailed to nextra customer support and their nodal officer and call to customer services but all my effort got in vain. I want my security amount of router get refunded as soon as possible. Consumer complaint has already been notified but no action has been taken yet by nextra company. Many times you have also notified to nextra compant but nextra diad not take any action to collect router and refund my money
