HORRIBLE, TERRIBLE SERVICE

I was due for an upgrade in Oct so I used vodacoms chat site to get some info After a few minutes the chat disconnected and in 5 minutes this girl phoned me. I had queried whether I would have to pay for both contracts if I upgraded my original contract cost R435 and the new device was R79 as I didnt wan to pay for two contracts I had emphasized this many times during the call to which she rep**** I would only have to pay for data used till the new contract took effect she said I need to pay R160 admin charges which would go off in my next debit. So I did the upgrade over the phone I received the new device. In the beginning of Nov I logged in my account and an alert came up saying my account was in arrears and I need to pay R160 immediately. I saw my next billing which showed I had to pay for 2 contracts. When I had queried a lady phoned me and said that the arrears is a mistake and that I will have to pay for both contracts till Jan and I was misled but she couldnt do anything she sent my query to the upgrades dept and I am not getting any help, SUCH PATHETIC SERVICE!!!
