I transferred coins to Polo nearly 60 hours ago & they never appeared in my wallet, I lodged a support ticket & shortly after they took it offline. Coincidence?
I once had an issue with a transfer to to Polo, but that that was because I typed the payment ID incorrectly. Due to the nature of Cryptonight coins, I think everyone sends it to the same wallet at the exchange, but that the payment IDs differs. This means that they allocate it to your account based on the payment ID. It is like depositing money in a bank account of one bank at another bank. You deposit it to the banks account with that bank but with your unique identifier in the reference field and this is how they know it is yours. If you don't use the correct payment ID, it will remain in a suspense account until correctly allocated. It is very complex to pay with CN wallets and very easy to make a mistake with the payment ID. There is also no way to correct a mistake and once you press enter the payment is done without a chance of confirming the details. It is very cumbersome and time consuming for the exchanges to correct user mistakes, find unallocated coins and allocate them correctly. This is however a universal problem and not isolated to FCN as far as I know.
Have you checked that your payment ID is 100% correct? I make a copy of each payment and paste it in a separate doc for future reference.
Yes it was correct, I too have my CN transfers 'commands' in a txt file so I can just copy & paste into the wallet
