Bro you just have to fill your information correctly . It the problem still persists then contact blockchain for further information for your problem.
Ii is not always an information filling mistake, sometimes the transaction gets confused , one time I have received a payment it showed up on my wallet activity but it was not added to my balance so I had to contact the support , and they told me to provide them with transaction ID and they fixed it , so always make sure to check it whenever you get funds into your wallet.
