Telkom - no accountability

I think Telkom staff are taught they have no accountability & be ***********, how are customers going to report us anyway. Telkom gave me an upgrade in August & internally someone at Telkom cancelled the order! It was only noticed when I queried this. Then my account was credited but the guy who I was emailing never responded to me for weeks. (Apparently he had left)Then I was overcharged again and I can't get someone to reverse it. Yes the Managers at Canal Walk are aware of issues.... AND... went to Kenilworth today and it didn't end well. I also wanted to upgrade a contract. Aaaargh....please will someone help me.....
