Terrible Service

I am very frustrated and unhappy with regards to the service of Telkom at Canal walk, in August this year (2019) I reached the end of my cellphone contract, I then upgraded my cellphone contract through Telkom Canal walk, I opted for a deal that I saw in their special deals booklet, the deal was a Huawei P30 which included free Hauwei Psmart 2019,The deal consisted of a 2gig data and 100 min all network airtime for R549, However I've been billed for the month of September R1014, for the month of October R1075, I've been mislead by the sales consultant Ashraf, He did not put me on the contract that desired at the time, when I expressed my unhappiness at the branch I was told its not the first time he did this, However I still haven't been helped, The manager at Canal walk Grant couldn't help me neither could the Telkom call centre.
