Bad customer service

Had the worse experience once again. I keep telling myself not to deal with Mtn anymore and this time I'm really done with them. So they called me to open an additional data contract which I agreed on for 40gb for R199. So they delivered it today, to my surprise they sent me 2 sims, I call Mtn to find out what's going on. Spoke to 15 consultants who can't help me. Been on the phone for 2 and a half hours. Finally got a direct line I could call after the 14th consultant. Spoke to Theron from Cti who gave me some clarity on the problem. He helped me very nicely. Told me that they sent me 2gb and 5gb sims. He said that he is going to log a complaint and have them listen to the recording and will get back to me after 24 working hours. The worst part is the manager of the sales agent even confirmed my contract and still send me the wrong deals. Mtn should really train their agents properly before letting them deal with their customers. I am definitely changing networks after my contract is done. Their service is ****.
