Wrong contract loaded and won't fix 6 months

Vodacom, I have given you 6 months to honour a contract deal you had in October last year on the Note 4 +free Gear Fit at 529 The cresta branch refused to give the deal despite the adverts saying there was no deal code. Your escalation department told me they would redo the contract by cancelling, reloading and phoning me to collect the watch. The only thing that happened is the contract was cancelled and changed to smart medium at 599pm. I want the watch you owe me and the reversal of the additional smart medium fee. I am tired of fighting with the escalation team getting calls saying you are waiting for the store manager or simply ignoring my emails. Reference from your escalation team isS3-1TH2E-EM90F
