sir, I had been to Singapor for a month. Before proceeding I actvated international romming services. Noe I returned to Ahmedabad (India) I request to deactivate international romming. Ihave told by the customer care official that there is no such provision to deactivate international romming and my Sim card is block, though there is balanca of Rs.111. I really surprised that there is aprovision for romming and for deactivate romming. This is eefinately unfair and un justified to block my Sim and put me in a very ockward position. Resulted that i have noother alternate to say by by to uninor. I further request you not charge any amount for the missed calls too. To maintain good relation please deactivate romming and activate sim card immediately.I also send request on 22nd May 2012 from singapor, however there is no response from Uninor. Please register my griavence and redrees the same without any delay. kanubhai Manilal Ajmera No.8401395394
