I called back the number (07) 3040 9887, rang and got disconnected automatically

This number called my mobile & left a message played half way through& oviously a recording about a purchase for $299.95. Stating if it is not mine, to call them back. Sounds like a scam so not calling back but checking here & there is no other comments listed for this number. Will check my bank next. If nothing will block number from calling again.
