Vodacom Hunky Dory Subscription ****

I have a contract with Vodacom and I receive R230 of airtime per month. On 12 April I realised that my airtime had been deducted at an alarming rate and I had only made 1 short call and bought R99 of data. I checked on my Vodacom App and saw that since 1 April, R10 had been deducted from my airtime daily at 7:30 ; in total R120 had been deducted from my account. I discovered that I had a Honky Dory and VIU premium subscription. I have never heard of or subscribed to any of these services and didn't receive any notification of my subscription. I cancelled both of the subscriptions. I have never had this problem before. I did some research and found out that many Vodacom customers have been subject to the same vile subscription ****. I expect to receive a full refund from Vodacom for the airtime that was ****** from me.
