bad attitude/cancellation of contract

i took my contract with telkom 08 May 2013 on my 061 no, was told im only now due for an upgrade. i go to the store they tell me only in September so as to stop arguing with them i bring a copy of the stating that i signed it in may. i go back to the shop today assisted by a lady with attitude & she tells that her system says in June. so she calls her manager a lady. they tell me according to their records it was cancelled & re activated in august & she does not know why.<br> <br> now all i want is to cancel the contract. according to my understanding i signed a 24 month contract with telkom for a contract phone if i dont want to carry on with their service i must give them a month notification. im trying to do that it seems as if it a problem. they didn't even take a cancellation form from me & said they will open a case. im tired of them, they never deliver. the did this contract wrong from the beginning, i had asked them for top up but was never done. can it be so difficult to cancel a contact? as for the staff member with an attitude hey im black they can do as they please & talk to me as they please. I was there today at the shop from 12:15 until 13:30. im just tired of them.
