Disregard for safety of personal information

I took up a seemingly good offer from mobile talk but was totally shocked that I had to hand over a copy of my ID document to a third party(the courier company) When I called the call center to complain I was told it that is how they do it, take it or leave it. If they have so little regard for the safety of my personal information what is the level of service going to be like? They could have allowed me to personally hand in the needed documents at one of their offices but I was forced to compromise myself if I wanted the deal.<br> <br> I am deeply disappointed with their attitude
