Regarding my sim

am writing to file a complaint regarding my experience at the Vodafone Idea (Vi) service center located in Laxmi Nagar, near Nirman Vihar Metro Station, on 4 October 2026. My prepaid SIM card was lost on 3 October 2026. Therefore, I visited the service center on 4 October to request a replacement SIM for my existing number. However, I was informed that a replacement SIM could not be issued because only four days had passed since activation and my documents had allegedly not yet been verified. As I urgently needed access to my number to log in to WhatsApp for business and internship-related work, the representative suggested that I convert my connection to a postpaid plan. I was informed that this was the only way to obtain a replacement SIM immediately. I was also encouraged to convert my other SIM connections to postpaid, which would result in a monthly bill of approximately ₹827 along with a registration fee of ₹260. Several hours have passed since the conversion, yet my SIM remains inactive and I am still unable to access WhatsApp. The representative provided her contact number for assistance, but despite multiple attempts, she has not answered my calls. I also requested cancellation of the postpaid conversion and issuance of a replacement SIM instead. Initially, I was told that verification had already been completed and the request could not be cancelled, even though my photograph had not been taken for verification at that time. Later, I discovered that cancellation is reportedly possible within 24 hours. Despite this, I have been unable to contact the representative to process the cancellation. I request an immediate investigation into this matter, cancellation of the unwanted postpaid conversion, and prompt restoration of my number through a replacement SIM.
