Hi folks, saw a whopping 90 CHF for 18 premium messages from number 667 - had no idea what it was for. Called Salt customer services and they told me that there seems to be companies who would somehow get you to subscribe unknowingly eg when you subscribe to get notified for something etc, and then charge for each message received - bottom line, Salt/providers can control this by blocking premium services on your phone - so immediately did that for all our subscriptions.
They are looking into how to reimburse 90 CHF so fingers crossed. I will also dig into as to how did the other company get to initiate the service to start with- to me it looks borderline fraud.
p.s. salt has a search engine to find details on these short numbers
