Bigman KG **** me

Bigman KG promise me if i invest R300 ill get R16500, i deposit the R300 then he said i must pay another R1000 for taxes on the money, i did send the R1000 after i send it he said i must pay another R3500 to release the money. I ask him to pay back my R1300 since i dont have more money he insist i must pay the R3500. I suspect he is a heartless ****mer who take granted of people who financialy struggle
