You have posted your phone number and email address in a public forum where scammer's, spammers, and robo-callers can see them. I'd suggest you press the three vertical dots at the upper right corner of your message and edit them out.
As mention by @makaiguy, when providing personal information, please send that information through a private message (PM) as we highly recommend not posting personal information in a public place.
