Ems couriers, disappointing and falsely advertising as a fast courier service

I asked my mother from Japan to send some documents I needed to apply for a visa for my spouse and child. The point was that I needed it fast, I expected to get it within 5 days and it took over a month! I was tracking it the whole time, it seemed to get stuck once it arrived in the country for about 2 weeks. In the end it said delivered when it was not delivered to me. Took a while after some phone calls to find out which post office it was at and I had to go pick it up myself. Will not ever use them again.
