Very angry client..you need to stop now

Super annoyed and very un happy with the service I keep getting at Telkom,I've been with this service provider for years now and over the years,getting through to a consultant was a mission but now they have improved so well,thing is I dnt think they train their stuff to well So there is competition/promo they are running which is called tap2win and I have been playing that where I got different prizes everytime I played and now I wont a R150 voucher and I wanted to use it,may I also add tht I was very happy when I got it but hey can I use the voucher? No since I never got any ref number on how to use it or how to redeem but I kept my cool and called in. First I got a very nice lady by the name of Thato who explained their systems were offline and like a patient client I understood and I called a bit later on,got a guy who tried by all means to muble his name so tht I won't know what he said,still I listened called the following day still no help instead this lady now ddnt knw what i was talking abt,was sent to hold don't knw if she was still asking or what but It was a long time,called again Siviwe was very helpful and said someone will call me back but tht was 3 days ago My point is why run a faulty competion? Why don't you teach your agents on how to handle cx? When is Telkom ever going to improve its service? When will we get what we pay for?

And I need correspondence from someone who will know what I'm talking about coz this is not customer service and we as clients are getting tired of this,it's annoying and unprofessional
