I do not understand why would a company claiming to be leader in the market does not have any technical helpline number. The number given (080-40020000) does not work. About transmission, pathetic and frustrating. Few channels have audio set to maximum and some have so low audio quality that the volume needs to be set to maximum to hear. Some channels have audio like it is transmiting telegraphic msg. This kind of service has proved that there are some things that should not be brought just because its cheap. Guys, think twice before u choose DIGIVISION.
