i got this too

Got the same message! I wouldnt ring them back if i was you! reckon it some type of scam!

Got a text saying to ring this number as they have an important voice message for me! But when I ring it, it just gives a few rings and says the number is not in service?

Got a call. then a message saying "you have an important voice message, call back to hear it". but can't call back.not even a ring tone is heard.
