I received same call. Left voice mail saying "khel bharat se chaubiso ghante"... thats it. They never said anything else... I couldn't figure out what was that about... may be another scam...
I did not understand the message or the language. If you reply or call back, then "you have established a relationship with the business." Then, as per law, they can call anytime they want. So, it is a trick scam call.
