So I have a problem that has been ongoing. I work with a few girls who constantly annoy me in terms of always asking to switch/change shifts. Before you judge, I played their game for a long time with no complaints. Now it's just become expected and annoying on their part. Same goes for my boss. I want to block them completely from texting and/or calling my cell. When they text me I want them to get an error message back that the text could not be sent. That way I can just tell them I'm having issues with my service. They aren't smart enough to figure out that I'm lying to them. I also want their calls to be blocked. If it helps I have an iPhone 5 on Verizon Wireless. Thanks for any and all help.
