I would like to port out

I got 1G of data 2 days ago and it's the 3rd day and I'm sitting on 270MB Like what the hell I only use WhatsApp and Facebook sometimes because I'm forever at work This is not the first time I bought 600MB begining of April and they lasted for only 2 days I'm ****ed coz even Lil data you purchase lasts only a couple of hours. Even though you didn't use much of the internet I would like to port out How do I do that
