Poor customer service

Good morning

I cancelled a contract 2 months ago and opened a new data contract. I was told that I could not use the sim card immediately but had t wait till 1st of the next month in order to use it. Apon using the new sim it did not work and after a month of back and forth I discovered that my contract was not cancelled but the exiting one was renewed. I have my reasons why I did not want it to be renewed. In order for Vodacom t cancelled the contract that I instructed them to cancel in the first place I have to pay a R6000. Why am I being punished because the consulted did not do as unstructured. Vodacom needs to explain to me. They just pull up their shoulders and it unfair. How do I get this sorted? I need a reference number so I can refer this matter to the Ombudsman
