This Cordiaip is worst than the worst. If you want to make a connection with this, is simply wasting your money and most of the times you will call from another network.
So you are paying double instead of single. There are so many good Companies than this. I strongly suggest don't use this super worst network. I have no words to explain how disgusting is.
You have to find new words for criticizing. I will give -10 rating for this. You no need to pay them for month, Infact they should give money.
That much of headache they will create. So folks, Do not go with this network at all..............
