I have a Cricket ZTE Score, model number X500, Android version 2.3.4 and I downloaded two apps- Mr.Number and Calls Blacklist from Vlad Lee. Both worked great, but once I deleted the apps, the numbers are still blocked. I unblocked them before deleting the apps, but when I could not get it to work, I deleted the apps off my phone and the numbers are still blocked. What can I erase on my phone to get the numbers unblocked? I've been trying to get those numbers to be able to call me for almost 6 months...even changed my number and it's still blocked! What can I do? Thank you.
