I AM BEING RIPPED BY TELKOM MOBILE ACCOUNTS

I upgraded my cell phone contract on the 19/12/2015 at Telkom in Cresta, Jhb. I was previously paying R369 for a Samsung S4 with 5 gig data. When I upgraded my contract on the 19/12/2015, I took a Huawei Lite for R200 with 1 gig data and a Huawei tab for R89 with 1 gig data. On the 31/12/2015 a debit order went through for R408 which is understandable. During the first week in January, I received a pro-forma invoice for the amount of R938.09. Since then I am trying to resolve this issue with Telkom mobile account. I was told that the January bill is included in the December bill. But the R408 has not be refunded to me. I will not pay R938.09 for contract that basically cost R289. I have never requested for Telkom to add the 5 gig data which was on my previous contract to the current contract. I would like my account to be credited with the unnecessary cost. If you are unclear, please revert to the contract I signed on the 19/12/2015. I do have R938.09 to pay Telkom in January 2016. Please sort my account urgently or stop the debit order until you resolve the matter. I will only pay R289, that is what I have signed for and maybe a little extra owing to the new contract.
