The simple answer is for you to simply not listen. Others ace interested, others comprehend what te is saying, and understand that nothing is 100% definite until the final document is signed in January.
There are many factors that come into play, including player injuries & other commitments.
My advice is to take responsibility for you not listening to what KR says, and stay off social media where silly rumours circulate.
Where KRs words "before the FA Cup game", or in the first week of January? Today is the seventh day of January. A week has 7 days. A signing may be made on announced today, or a signing mode and announced tomorrow or later in the week.
I think someone may need to explain to you that Father Christmas isn't real. I'll leave that to others, given how upset you are over no signings for a football team in the first 6 days of January.
