I've used this ATMa number of times and is in high street shop. Today I bought btc in two amounts because the machine ran out. The first time the coins turned up and an hour later I returned because they said they would restock and the machine worked again. However the coins have not turned up and there is no sign of it on the blockchain to the address I sent it to. What should I do?
The machine scans you're QR code.
There's an attack going on right now on the block chain, over 50 000 unconfirmed txs. So probably, if you're saying its not a scam, its probably sitting somewhere behind a backlog of fake transactions. You should contact support and see what the miners fee the atm uses- if it's less than 0.0001 you may have to wait a long while unfortunately
