Spam Text messages?

[brie0]

Okay so i had updated my snag-a-job profile and afterwards I immediately started getting spam phone calls/texts. This is a site I have used many times and actually got job call backs from so I trusted it. Not anymore obviously so I wrote them an email and had my account deleted. However sometimes I still get these odd spam text messages. I'm going to try to type and example of how it looks. I have an iphone: so the txt will be from 555-4444 and it will say
555-3333:hey what u doing?
555-3333:no im still at home
555-333: okay be there soon!
555-333: have you seen jessica?

Like i checked one of the numbers on facebook and these are actual people but its just one side of a conversation. and the messages come from another number which is strange. I block the numbers as i get them but my main concern is if i can read their messages can they read mine? Its never in the form of an imessage though just as regular texts. has anyone had a similar problem?

Delete your account from snag-a-job if your don't want to continue or deactivate it make it active when you need it....

If you have an iphone then just block those numbers.
