Took up too much space on cell n ran constantly in background. Was using over 3 GB OF DATA IN BACKGROUND in just 2 weeks. Was killing my cell & my data. Big no no. I was approved in Feb for 2000..00. tried to shop in store. They didn't know how to use. Thought it a scam. So went home. Gave up. This month (March) trying again for hubby's bday for only a few hundred purchase Now I log in and says zero credit.. they're sorry. Like what. My credits all increased since last month. I don't get it.
