Cold call: Supposed Trading account opened in my name

Got a phone call from Liberte Solutions that supposedly works with the JSE (btw... this sounds like Liberty over the phone, giving it **** credibility). They told me that an indirect trading account has been opened in my name and that it is earning 25% (just that.. no term, no anything). And wanted to book an in-person meeting as soon as possible to take me through these options etc. Then added that this was an educational service provided with the JSE.

I found this call very upsetting. It sounds very *****. They could not give any details about this supposed in-direct trading account that was opened, or about the returns that it is supposedly earning, or about the assets that could be traded with this account.

This whole thing was just ridiculous and unpleasant. After a while of not being able to answer any of my question they just hung up.
