I’ve sent off this email and hope they at least investigate this as it’s all too fishy to me personally
“Dear sir/madam,
I am writing to you regarding the postal service we are not getting. This is the second time I have had to write to you on this matter.
Since November of last year we have had items never arrive at our post-box – the latest thing to go missing is leading me to believe that someone within your organization may be stealing items from the post. I shall explain why I believe this is occurring.
