@BoloBolo63 , there are plenty of answers here if you looked at other threads, but here goes.
Try uninstalling and reinstalling the app from the App Store, if that does not solve it, ring customer service to reset your account. You can also log-in via the website to your account and gift data there.
To contact EE customer service dial 150 from your mobile phone or ring customer service for free using Skype or another phone: +44 800 079 8586 or +44 800 956 6000.
