Has this ever happened to anyone before? I can reach others but when they call me back, or use the number I send to them, or try to text me, I don't receive anything. They told me they all reach a (probably the same) stranger.
Thanks to both @LEGO and @computergeek541. I contacted the Moderator_Team, the back and forth took forever and why on the earth a Twitter account is needed... While waiting I found I could change the number myself. So I did so. Problem solved. Thanks...
