I regret calling the Vodacom call centre for a solution and being a their customer

I have been struggling with a subscription that has been activated on my number and every time when I cancel it. A week or two later I will receive an sms saying that my weekly subscription will be renewed. Today when I receive same I decided to call to ensure that my airtime does not get taken, unfortunately, a rude and unwilling to assist agent answered the phone. Words were put in y mouth, so many things were said with a bad attitude and the next thing I was transferred to Namhla who assisted with great pleasure. I have been a Vodacom client for more than 10 years as a prepaid customer and then had 3 contract and I cancelled them because of this kind of behaviour with them. As am speaking am waiting for another stupid company to continue taking my airtime. I would like to port my number , please assist. Am tired of Vodacom's strategy to make money.
