Fed up with subscriptions

Four years ago I bought a Wi-fi router on contact from Vodacom . Up until now I haven't had any problems. I upgraded the contact in June 2017. Since November I have been getting these subscription chargers on my Vodacom invoices. Since then I have paid R1291.17 towards "subscriptions" and "content services" I know nothing about. I have left it till now but it is really getting ridiculous. I have phoned customer services but all they say is that they can not control it. Accidentally clicking on an ad or pop up does not mean that I give permission for Vodacom to add money onto my account? After being a Vodacom customer for 13 years, I am really considering changing networks as soon as my contract is up. Then you can stick the 'R15 a day' vlive subscription, that I did not subscribe to in the first place, where the sun doesn't shine. I have no problem paying for extra data that I used during the month but please don't charge loyal customers for something they did not consent to
