Vodafone India — harassing for fake outstanding due

Address:

201306

I have ported out from vodafone around 6 month back due to poor network at my location. Complained many times but no remedial action taken. For porting out, i have made advance payment against my bill. They rejected my porting request twice and after escalating they have accepted. Now after 6 month they are calling me and asking to make due amount if rs 1200. I had plan of 499 and 199 for my 2 number. I don't understand that if there was any outstanding then why my number ported out. Also, if i have made advance payment then why there is outstanding.

They are frequently calling on my and my wife number and harassing us with very unpleasant behavior.

Thanks
Gaurav
