Vodacom ***** schemes

Good day, im very dissappointed in Vodacom. Im years with them. From time to time i have an issue. Someone from Vodacom phoned me to change my account ..so it can be cheaper, and it also is due for upgrade..I believed her. Long story short, my account is * now almost double...it has all sorts of admin fees and ,,step in,, fees..All the time THEY PHONED ME out of blue? Never ,,step in,,to ,,repair shop in Durban? Im in Gauteng? Got R45pm phone included..thats fine..but the whole story is ,,*****elent,,? 1. *Why say you phone from call centre, (if its repair shop) *charge me higher than i paid previous,and *also charged me for walked in office? * Why phone me for one phone ...and my other phone..just extend the time..no changes,and charged me for 2 contracts changed? Then deduct R720. From my account if you dont have mandate to debit me more as R500?.. *** Please pay back my money!!.. and rectify that deduction amount...or cancel everything!! Few years ago you sold me an G2...Tablet..The thing is so slow...its of no use?? Your geand children can play with it!! Thats only use of that..!! And it was a callcentre story also!! Cant even ask Google something..they so slow!!, days! Weeks!! Never seen that!! Pay back my money,please..Tired of fighting ..
