It is incomprehensible that such a bad company is not closed. They are unable to send a package from A to B. Apparently, quality is a strange word. A logistics company should understand that if you take a package to send that you must have a receipt address that is complete? No do not belong to GLS. There they only understand when they have to deliver it. And it doesn't matter if you point them out to the problem in advance. Those depots are only a few of them.
A phone number cannot be found. It is best to have your package delivered somewhere at a point. Delivery is a big drama.
The worst thing I think is that this is the second time that it goes so wrong. I will then send info on time so that they can correct it, but that does not help. They don't care.
