Review Lazy Post man

I've been checking my letters to this Post Office for my overseas letters and to find out the letter I should received earlier was there for almost two(2) months!!I keep asking them last July and they told me the letter has not yet arrived then last August I've been asking them too and no result. To my surprise the they said the letter has arrived now, (September 10, 2018)and yet they don't deliver. I have to personally get it at there office.The stamp on the envelope I've received was sent dated July 09, 2018 and they received the letter on July 24, 2018 at the Post Office Santiago City Isabela and yet they don't deliver it.I just get my letter yesterday September 12, 2018. attached photo as evidence of their poor services!!!
