Poor service delivery : Telkom Clearwater

ON 2021-06-19 I proceeded to Telkom Clearwater to cancel my mobile contract which expires on 19-07-2021. I was informed by an agent to come end on month to cancel contract as an early penalty fee of R800 will be charged for early termination of contract. I informed the telkom agent I need to give one months notice but they did not want to address the issue further. I went To Telkom Westgate and they informed me since i did did not give them0n one month notice, the contract will only terminate on 2/08/2021. Why is there double standards by two different branches. Had Telkom Clearwater iniatially entertained my request for cancellation of my contract my contract could have been terminated 0n 17/07/2021. I have to pay another subscription of R651.70
