Blockchain ****

I received a call from Blockchain a trading company telling me that they have been put in charge to pay out all the capital from a company called Coinlife seeing that Coinlife has been closed down. They gave me a figure of how much of my capital is in Bidcoins and that they can pay me out in either USD or in Rands but that it will cost me 17% of the value of my capital invested in Bidcoin. Here comes the angle for I must pay this money upfront for they are not allowed to deduct it from my capital they have to pay over to me. I asked for proof and a certificate from them as proof thereof but up to date have not received anything. I sent three email to the companies support side but also still have not received anything from them. It seems that this is yet another **** company like Coinlife trying to steel money from people. Please be careful of this company by the name of Blockchian for you will not get your money paid out to you.
