*****ulant Upgrade

My fianc? has a contract with 8ta since July 2013. His contract was due for a upgrade now in July 2015. On Friday 10 July 2015 when we went into the 8ta store in The Glen shopping centre to ask them not to renew the contract. 8ta then said no sorry it is not possible the upgrade is only due in 2017 we immediately said its not possible so they checked and said that my fianc? already renewed his contract and did his upgrade in February 2015. How can this be possible??? There is no supporting documents to prove that he upgraded and he has no device for this \renewed"contract?? So he paid R800pm since July2013 for a 8ta 15G sim and a Tablet device and now has to pay another R800 pm until July 2017 for the same device and sim??<br> I will not let Telkom get away with this"
