Waited over 3 months for Smart Premium extras

Such a long story, took up Internet contract mid last year but was overcharged. Tried Internet but never received single response. Went into branch and took up Smart Premium to try increase ****py internet. Took months to sort out the over billing ( got a credit eventually but no recon can't see if it's correct), I had to beg and plead and scream. Internet still ****py on new 10mg line and had to go into branch today and cause a scene to get my Explora and extra SIMS etc that go with the Contract. Gordon ignored my emails and calls ( and it's impossible to reach the branch via telephone). Then he seems surprised when I pitch up there and cause a scene - I warned him via SMS prior to going in. Begrudgingly gave me all my extras, no explanation as to why I had to wait 3 months for my goods ( they were right there in the shop), no apology nor remorse, and just such apathy. I presume the staff there are not working for free, it's their jobs for which they are getting paid a salary. I am upset that I had to stress myself out so much over such a stupid thing, over such a long time. My internet still ****py but don't have the strength to go into that now even though costing me over R1kpm
