Contract cancellation

I did an upgrade in Feb 2018 on one of y numbers, I then went to one of the Telkom stores in Southgate to confirm when my one contracts will be ending this was January this year I was then advised that the contract will be ending in Feb on the 11th I proceeded to log for the said contract to be cancelled at the end of Feb. I was advised that an agent would call me in 72hrs to go through my cancellation no one called just got a sms that my reference had been resolved. I got in touch with Telkom and was advised that my contract would end on the 5th of May 2020.

I advised the lady who was helping on the chat that this is not possible as the contract was taking out in Feb 2018 and that I had already been in store to confirm this. I then went back to store this time went the Telkom store in Mall of the South and the lady assisting me advised me that she can see that the contract was upgraded in Feb but doesn't understand why it ends in May she logged another call to investigate this further again was told I'd be contacted in 72 hours but again no one did and all I got was sms saying the ticket is resolved.

I called again today and was advised that it end in May because I did an early upgrade in Feb that is why. This was never explained to me when we did an upgrade I signed a 24 month contract with the new FreeMe 1GB package moving from the smartplan100 and was advised that this would end in February.

I would like for that to be please honored and my contract be ended at the end of Feb and the number be moved to prepaid.
