Vodacom and wasp companies (befit), *****ing from customers

Spoke to vodacom today as I have been losing airtime. They informed me that there are two apps that I am subscribed to (wasp), befit being the first. They have been taking R7 a day since 11th November 2019 (R833 in total). I explained that I hadn't subscribed to any apps (I know this yo be true as I dont subscribe to anything on my phone, nor do I reply to any of the SMS's that come through on a regular basis trying to con you into subscribing) The lady from vodacom tried to tell me that its easy to tap on something and subscribe.... trying to make me feel inadequate and that it was indeed my own fault. This has happened now several times, and vodacom excuses are becoming tiresome. Vodacom and the wasp companies are nothing more than low life thieving ****!!! It is *****ing, plain and simple! How is this legal??
