A while ago I bought 500 Mo and even though I can still see on my account that it's there, I can't use it! I've tried going to the store so they could fix it but they told me that I need to call from my phone. So once I got home, I called and waited around 2 hours and still didn't get answered so I hung up. I've been on many websites and Q&As but whatever method I tried didn't work. When I try to use my data it says that I need to turn it on (even though it's on) or that I'm not subscribed to a cellular data service (even though its says that I still have my 500 Mo untouched on my account). I've been trying to fix this problem for a while now and it really frustrates me.
