Telkom is the worst service provider!

I took a cellphone contract that comes with 1 GIG data in February 2017. In January 2019 a colleague told me that I must cancel the 1GiG even though our contract was for 24 months (this was never explained to me when I took the contract). I went to their branch in Mutual they told me that I must come back when my contract has expired. I went there again in February 2019 a consultant told me that they can't assist I must cancel it online otherwise they'll continue to deduct even though I'm not using the data. I was very upset because they were supposed to tell me this when I approached them in January. I tried to do it online and failed. I phoned their call center and spoke with a lady named Sinazo she assured me that they will cancel it, to this day nothing has been done. I am very furious because they are still deducting, I want Telkom to REFUND my money and CANCEL the damn contract!!

My number is ********** 503 (Siyanda)
