Vodafone — Blocking porting out despite paying advance payment citing false contractual obligations

I sent a port out SMS to 1900 on 31/10/2022 at 10:24 AM followed by 44 sms messages until 02/11/2022. There is a standard false message stating that UPC cannot be generated for the reasons:(1) There are subsisting contractual obligations with your service provider. Advice payment of Rs. 900/- was made on 31/10/2022 at 10:31:34 AM duly acknowledged by Vodafone India vide their Email dated 31/10/2021.
Thereafter on 31/10/22 at 09:07AM I received a call from[protected] wanting to know the reasons for porting out. I emphasised the on network issue and they abruptly disconnected the call.
Same procedure was adopted on: 01/11/2022 at 10:04AM from a call originating from[protected] and[protected] at 11:40AM, 03:26PM and 06:16PM. The call is abruptly disconnected This illegal act breaches several provisions of the law. I need the PORT OUT Code without any further delay.
