I think I have to. It's absurd.
I broke the 5gb mark. My phone was rendered unusable for data. Not slow, unusable. The data was so slow that basic Apps on my iPhone 5s (maps) would time out. I accidentally left Podcasts downloading overnight without WiFi. I had to go 75% of July with this data issue. Of no data.
Now, I check my bill, and I see that, while I was on teh treadmill tonight on airplane mode, I somehow had two 20mb downloads.
I will be filing suit. And finding an ethical company.
