Tata Sky — tata sky broadband connection shifting

Address:

Flat no 547 plam groves Apartment, Marsur Village, Chandapura, Bangalore Karnataka 562106

I am using tata sky broadband internet service since 8 months. Recently i have shifted to new flat in same apartment. I want to shift my broadband connection to new flat. I have raised request for shifting on 14th of jun 2020. As per tata sky service provider it will get shifted in 48 hours.
But it's more than 11 days my connection is not shifted.
I have called many times to customer care executive they are giving promise that it will be done in 24 hours.
I am working from home and i have very urgent requirement of internet connection.
