Hello,
Is it a scam for sure ?
One month ago I got a mail from startmining (Andrey) which told me how to get a refund. In the mail there is few steps, some things to do on MyEtherWallet to get the refund but I don't see the team talking about it here so I didn't take it serious. Did someone else got this mail ? Is it a good idea to follow those steps and try to get refund ?
Well, here you answer your own question:
One month ago you were promised a refund - have you got it yet? It does not take that long to process refund.
If not = scam!
