21 Sep 2018. A buyer from Gumtree was using WhatsApp-ed to contact me said interested to purchase the Iphone X Max that I listed on Gumtree, and he said he's buying it for his daughter birthday present and he's at offshore working. We exchanged some messages and later when i deleted my information, he sounded angry. He said like “Wait for more problems to come” in threatening way. He captured the transaction receipt from Bank of America and sent it to me.
