Vodacom Hunky Dory ****

I am on prepaid, I have noticed that my airtime is dissapearing without me making calls. I have just learned that I was subscribed to Hunky Dory and from December 2019 to today they have taken 37 transactions amounting to R370. I had never subscribed to Hunky Dory. This must be a **** from Vodacoms side. On the billing it says Vodacom account billing. What are you up to Vodacom?
