Vodafone India — wrong billing & charges

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201301

Hi i was a vodafone customer in post paid mobile services till july 2018. Post july made a port out in airtel. Port out request was submitted post clearance of all dues and charges. Now again vodafone is calling and asking for 1302/- additional charges for the services which i have not availed. Will not pay this amount. Please look into the same as having daily calls from customer care.
