it is getting worse and painful

vodacom service is getting pathetic, the just for service was a great idea from day one, now i lose my minutes every time i buy them. i always buy the 10min over 2day . if i don't use them they disappear. what does over 2 days at vodacom mean? this happened twice last week, with out script questions the agent helped me. today i lost more than 30 min i called in and Thobeka took my call. firstly she was focused on the call, did not authenticate me, made me repeat my number 3 times. after clearly explaining what the problem is, she wanted to read her script which had nothing to do with why i called in. worse part was when told the 2days minutes are actually for one day. like what s going on at this call call centers? are they being told to lie and be rude.
