Subscribed to WASP services without my knowledge or permission!

I'm a Pay-as-you-go Vodacom customer and have been for as long as I've had a cellphone. I normally top up with R50 airtime at a time, and then buy data for R29. Over the last while, it's felt like I've had to top up more often that normal, but since I'm not subscribed to any additional services, I figured it was just me running out of data and then that eating into my airtime. Nope. This morning I noticed that R20 airtime had just disappeared, without me making phone calls or anything. After googling a bit, decided to try SMSing 'Stop all' to 31050. Within a minute I received multiple SMSes saying that I had been unsubscribed from ExploreApp, BeFit and Fun Chat. All services that I NEVER subscribed for.

I find it unacceptable that a customer can be 'signed up' for a service that they never agreed to. Who knows how long these people have been deducting R20s from me?!

Since I don't even use airtime very often, I think it's definitely time for me to switch to Rain.
