I got shocked to see my matrix bill. There are so many hidden charges, which they wont share while taking the connection.
I hardly used my phone. I kept my phone switched off most of time during my usage.
But still I got 4700 bill for 1 month.
Here is how they will charge.
Surcharge for each and every call you make
25% of you rental as Setup charge
Surcharge for again rental & setup charge
They will sum these setup, rental & usage charges, and they will put again service tax 12%. On top of this, they will take the highest USD to INR exchange rate on the day they calculate the bill and generate bill for you.
I lost 2000 Rs/- just because of hidden charges. Friends I recommend dont buy matrix calling card.
