HELP!!! / MoonPay

I just bought ethereum and when I view it on the block chain it says under STATUS: There is a pending txn with a lower account once. This txn can only be executed after confirmation of the earlier Txn Hash#

And the TxnHash is a link I can click and it sends me to another transaction. But the ethereum never showed up in my wallet. So I'm not sure what I'm supposed to do ? Anybody know can help? Would be much appreciated 👍 I used MoonPay.
