Lyca must have been hacked, sold their mobile numbers with the simm card number (the one one the back of the simm card) I received a call twice on my Lyca number from non English speaker giving me forged news about the lottery won be me. To assure me he read out the simm card number and then we had a long conversation. He also emailed me the forged lottery certificate to myemail address. I understood it was a fraud but didn't expressed it. Eventually he wanted me to send £500 via Western Union to Dubai. Upon which I challenged him and he dropped the call. My wife had been called in similar fashion. And one of my friend actually paid them through Western Union and lost his money., I am not sure how to report this sort of fraud but highlighting it here so that appropriate action can be taken.
