Need to Activate my decoder without any helpful assistance (useless)

I need to activate my decoder and I have been on the phone a thousand times yesterday and today and been cut off all the time, I have send now on facebook, whatsapp and tried via my cellphone to activate it and now getting an E155 on my cell and still no channel on my decoder, this is extremely frustrating and I am getting now upset as the call center used all my airtime up...... which is unacceptable 1st and 2nd my decoder is still not activated, 3rd you not getting anywhere with this guys I mean what is the use that they are in a call center "this is you job/work do it....." I am not impressed with the service I received and that as a new customer...... I want a manager to advise me when my decoder will be activated and working as I have done everything that I should and I am not going to getting a technician out to fix the problem if the problem is with the call center.
