NO ONE ASNWERS THE PHONE!!

I've been trying to get hold of Telkom for almost a month now, phoning for days on end even holding over the phone as long as for 52min simply for a call agent to answer the phone so I can apply for LTE uncapped package Telkom is offering. I've tried phoning to different departments just to ask a consultant to help me, and they simply just ignore me and put me through to the LTE department where yet again NO ONE answers. I've never experience such bad service in my life, and it leaves me with no other choice as to change my service provider.
