Hathway — Made me pay for the new connection by making fake promises of offers for the new connection

Sales man made fake promises of providing 150+ tv channels and ott subscriptions with 300 mbps speed WiFi .Just the WiFi has been installed and data speed is not as promised .no OTT and no TV channels which are promised .when tried contacting him, salesman is not picking up the call and when complaint has been raised Hathway is ignoring for whatever had happend .They simply looted around 3k from me and now no body responds
