Airlink.in — Loss of connectivity

I was not able to access the internet so i have registered ab complain in the airlink through whatsapp and through message. I waited for 3 days but there no single reason from there side. so after that i call on there customer complaint number and talk to respective consecutive. so he registered my complaint again and said we will sending technician on the same day or else next day. But next there was no response from there side. Again i call to there customer number but again the same reply was given to me. so next also same situation happened no response from there side. Again i call to there customer care number and again the same answer was given by the executive. So i had complaint to the local technician of airlink for solving problem and he also gave me the same reply that he will send technician. There no proper respore from there for the problem.. Its almost 9-10 days but there no positive response from therr side. The worst internet service provider ever
