Sir,
I am Sakthivel. N from maduranthakam, my mobile number is 91-9094080353. I would like to change mobile service provider (Portability) AIRTEL TO VODAFONE, but airtel network is not allowing to change to vodafone technically they are not supporting. Most of the time I contact to the customer care there is no option to change the portability, and computerised voice says that try again.. try again.. and it says "INVALID PORTIN NUMBER". I request you to intervene and solve the issue immediate basis.
