Spurious, Unidentified Premium Text Rated Message Charges

Deon we agreed on the last complaint I raised that Vodacom would track the source of the premium rated text charges on my account. I see those charges were reversed. I however today received a text from Vodacom today saying these charges come from 42402 and ***. I don't use these numbers on my phone and cannot identify where they come from. Kindly contact me asap as I have advised Vodacom to block all content and premium rates text message charges from being billed to my account. The reference number provided by Vodacom is ***. This needs to be blocked for once and for all.
