One of the reasons why the ETH/ETC deposit has not been credited to your wallet could be due to the deposit amount not exceeding the minimum deposit limit. In which case the transfer is stuck in a deposit address.
The minimal deposit amount for ETH is 0.052400 ETH.
The minimal deposit amount for ETC is 1.528600 ETC.
Making another ETH/ETC deposit will trigger the previous transaction if their accumulated value exceeds the minimum deposit limit.
Your deposits should be merged and credited to your wallet.
