Matrix Cellular (International) Services Pvt. Ltd. — Wrong Information

I am a student and doing my masters from United Kingdom. Before leaving India I took matrix sim card as they were promising very less call rates. But things were other way around as the local connections what my fellowmates are using are cheap comparatively.

Also I had given some voucher while taking connection which according to company agent was supposed to give me first three months waiver of rent. I did not get any such offer. The worst part is they took Rs. 5000 as security. Being a student I have to manage my expenses and I can not no longer use this connection.

So I want to register a complaint against matrix against wrong information and I want them to abandon this connection me refunnd my money.
