Airtel — Not closing my connection

Due to this pandemic situation of covid-19, airtel support not helping me and instead of it they make in mental harassment situation by calling me to karnataka to come and verify my address. It is just for a day such harassment even after that i simply called that verification guy and asked him what is the matter then he said sir we are third party verification you can send any friend also by confirming with third part i am able to verify myself. If i am not good person and my verification is false then how airtel provided me their sim and make to use for long time. Now at the time of closing they irritating me alot. Kindly do the needful asap.
