Vodacom took my airtime

Vodacom took my airtime in the blink of an eye without my consent. I had my mobile data off,this to prevent my airtime finishing without purchasing data yet. I then checked my balance and it was R79. I went and bought a just for you bundle of 1G for 1 day at R19. I recieved a message Suddenly saying that i have been subscribed to "Video Play", then incame the message saying that my 1gig bundle for 1 day had been loaded. I went to check my airtime and its suddenly R1.87. Bear in mind that i only bought 1 gig for R19. Meaning basically my R50 airtime is gone without any consent to jpin video play or anything. This is truly unfair cause all i did was purchase data not consent to anything. I was planning on topping up the R50 air and purchase a 10gig bundle for 7 days at R209 inorder to do work and school assisgnments but now that plan has went out the door. I am beyond angry and disgusted by vodacom.

I even have screenshots that can prove this
