Recently got Airtel Black plan. I was charged 2500 with same amount being credited to my Airtel Black account. They have provided WiFi 6 router even with the base plan. But the surprise is, I was using a local ISP and I told the sales person that I have just recharged my existing connection. He told me if I can provide the invoice for the same he will give me a cashback of 299 on top of existing offer. I did the same and after couple of days of installation, he refunded 299 to my personal bank account via UPI. So, if you are going for new connection, make sure to ask the sales person if there is any such offers available. Practically you are paying 2200 for installation to have 2500 as your airtel black account balance.
