Attention!! This is the second time a small letter size goes missing. I sent another letter just a piece of paper to see if it arrives and it arrived but the 2 which were a bit bulky( i sent a plastic mould and a phone component) they never arrived. So my guess is that the letters which seem interesting or a bit bulky can go missing. I am accusing royal mail of theft/negligence, it s clear as daylight that something is very wrong. I want to warn everyone to take due diligence because this is REAL. And they have no transparency whatsoever. The posts were from Uk to Uk address Edinburgh-high wycombe. Please i want my stuff back
