Nope still not fully safe its looking very good for you though

But they only need to POST it to you within 14 days if it takes the full 28 days to actually reach you not their problem they are a law unto themselves get no posting proof you can ever see the law is fully on their side if they say they posted it they posted it as far as the legal system is concerned
I pleaded guilty to mine posted back within a day 3 weeks tomorrow not heard anything back hopefully they just decided enough is enough but I am not holding my breath at all
A lot seems to depend on the severity of the offence as well. If your a new driver looking at 6 points & or a ban or your driving history is chequered takes them longer to decide what they want to do to with you!
