****ED UP SERVICE

So my contract got changed last year January from Cell C to Telkom. I wasn't notified. Then I dont get any notifications sms/emails cause obviously there is a new service provider. I called Saturday to say my bundles are going fast and not being notified is difficult. I got upgraded and was told 72 hours. Today is the 4th day..please calculate for me how many hours is 4 days? I called today and was told its not activated. Then I asked for the call to be played and was said they must request the call. I get put through to another agent which says it is activated but HE THINKS IM STUPID...CAUSE HE ONLY ACTIVATED THE CONTRACT NOW CAUSE I RECEIVED THE EMAIL TO SAY ITS BEEN ACTIVATED. I request a cancellation he says no lets fix it. Dean or Eugene will call today by 10:45...its 11:08 and I am still waiting to be called.
