Welcome to Android Central.
We'll need more information to offer you better advice.
You say "rejected" call list. Do you mean "blocked"? Rejected usually means that the call was not answered or instead of answering the call was rejected and sent to voicemail. Blocked is different and if you're receiving calls from your blocked list, how did you block the number? Is it just one number, all blocked numbers or random?
Please include more details because you didn't really say anything in the body of your thread that helps us.
