Vodacom contracts is a ****

I took a contract for data with Vodacom in 2022 (24 Months at R299). My contract was ending on the 23 August 2024 , on the 16th of July I called in asking them to cancel the contract the lady that I spoke to said she placed a cancellation notice . On the 21 August after the deducted R389 I called them ,I spoke to Vusi who said to me there was no cancellation notice , I told him I want the contract to be cancelled by end of August he said he wi escalate the matter to see who said they placed cancellation . He then advise that he will cancel contact effective 30 August . I still had 23 gb available from there the data never worked ,I called in again they said my contract is suspended . As I thought I am done with Vodacom On the 1st data is loaded on the suspended number and there is a bill I owe Vodacom . Initially when I took the contract is was for R299, without any communication or anything they started deducting R320 ,jiki jiki R350 ,sometimes R345 On August they deduct R389.
