Contract total cost R189 6 months in and still not

Is there any mobile network that employs educated workers or is it just pass the buck and get my day over. Now i am tired of speaking to idiots, please get me a manager or I WILL CANCELL this debit order. The contract was taken out in Oct 2014 , advertised at R189 total cost, however i keep phoning and keep getting cut off. My account has never been correct, each idiot promises it will be corrected. Then i am billed for calls, then sms bundles etc. The advert states R189 total cost with sms,s, data etc but i keep getting billed, can whoever not comprehend, what i am saying, Total cost R189, must i send you a picture, will that help. 50 anytime minutes,100 sms.s 100 mb data including tax at a total cost of R189, advertised in Nov 2014 page 12 Sony Experia M2 smartphone and not the waterproof model. I am going to set my deduction at bank at R189, if more it will be rejected, it can be done watch me, then we,ll see who runs after who, This is pathetic ,MTN what clowns do you employ, and we cannot phone as the call gets put down in your ear. Send me a mail in writing that this is sorted out, so i have the proof.
