Vodacom AKA Robacom

Horrible experience with Vodacom or should I say Robacom? I upgraded my contract October 2017, my new package offers two sims which only 1 was delivered I followed up with Vodacom and they promised to deliver, to cut the story short I have been following up since November 2017 only for them to deliver June 2018. I had to make several calls to try activate the second sim still no activation, the call center agents seem dazed they don't know process, they failed to escalate when i wanted to escalate apparently Vodacom call center runs without managers and team leaders poor call center agents with no support. I have been dealing with their ****py service for far too long , need a new network provider who knows what they doing and keeps promises. All the agents who tried to assist me failed dismally , do they have a quality department who checks these recorded calls? I doubt hence we receive poor service, am not getting value for my money. Palesa was the last agent who tried to assist also did not conclude, I want all the airtime I have been paying for monthly but unable to use , what a waste!
