Sim only data

Very bad...I bought sim only data months back from a guy named Donald in tzaneen but I did it through calls and email and he came recommend by a friend..R199 for 60 g but I was getting 40 g.on top of that he didn't explain to me that the data is gonna split (YouTube,showman and all that) and I was left only with 20g for everything I want to check online...if I knew it came in division I wasn't gonna buy it as I don't even use YouTube showman and all stuff.i just needed straight data nothing complicated...I'm a sad customer 😢
