Airtel — alleged hc legal notice issuance and anonymous phone calls although full payment is already given

Hi, got a corporate postpaid plan registered in airtel until last month it was put on a request for converting to prepaid from an authentic airtel store in r_a, kolkata, wb as required for not bearing the additional roaming costs anymore since the circle previously belonged to chennai, tamil nadu (Now put to change to kolkata, west bengal) to minimize the excessive billing of the postpaid a/c and sudden snapping off the network facilities (New bill cycle date to mid-july) for late payments previously. Now the last month of the payment for postpaid bill has already been dealt with, yet i am receiving anonymous calls from chennai regarding issuance of legal notice from high court by the party under payment dues and imposed fine of rs3k + which is neither fair not legitimate. This is the second time i am dealing with a similar consequence. I want to take immediate actions regarding this and terminate all further relations with airtel on this postpaid number#9*1. Even after the promise to activate the account within four days, at max, to the requested prepaid plan, still placing calls it is showing "not registered on network" even though there is visible tower (Maximum).
