I had a few missed calls from this number. I rang back and it was a Nigerian man saying god gave him my phone number in his dream, and god told him to pray for me. And that Sheffield football club will win something on the 19th may??? I find this very odd and even recorded the conversation. He was very pleasant and asked if he could pray for me. So I said yes, and it was uncanny how he said that "this person in your life is ruining u, go away"... Which means something to me. Anyone had something similar? Is it a scam?
