Cancel upgrade and restore contract as was

Case No : ***, ***, *** On 23/07 Tasmeehah Sheik called me at 08:55 and 09:13 to tell me that I am due for an upgrade if I ordered from her there is no add conn and other charges. I told her look on my acc she will see I do not use airtime and sms much because I still have a lot left but run out of data and I was thinking of cancelling my contract at the end of my term as it costs R399pm but if I could downgrade to something with more data about R150 pm I would take it. She phoned me back with options and we decided on the Zte Mf 65 router, 3Gb anytime data pm and 4Gb nite owl data for R189pm. I asked her more than once what will happen to the airtime and sms that I've got. She said I will still be able to use it till 5 November when the contract would originally expired but that I could already start using the router when delivered and that I will then start paying the reduced tariff end of August.<br> 1 Aug I lost all my data, sms airtime and is now on expensive 200mb!? that I didn't ask for with penalties and extra costs not explained or accepted and router only activates in 3 months. I do not want to wait 48 hours to be fixed. it took 5 min to mess up!
