Sir,
I am having mobile sim from your company.My no. is 9831185046 in India.It is unfortunate that my family members in India can not contact me to Algeria as I am supposed to get.I am having more than 15 connections in my family, By failing your service which u are supposed to render, I will be bound to cancel all your connections.
Pl. treat this complain very seriously.

With regards,

Kaushik Ray
