Airtel — Regarding relocation of broadband connection

I had taken new airtel connection in april but i have changed my house but when i tried to contact airtel for transfer of airtel broadband connection to new place they refused to do it. They all suggest me that to take a new connection. Earlier i had taken 6 months plan and still i have 90 days left. On their website it is written that it is very simple to relocate connection by making a call but i had called to airtel team more than 25 times. I want to resolve this issue as soon as possible. Hoping to hear positive results.
