I just wanted to let you know that GLS is useless. Do not deliver parcels to neighbors, causing delays. Then the track trace is not recognized on their own site (does not work on mobile at all). Then they ask to leave my phone no. Then should we hope for a call? Serious? Sun 1998! Better work with TNT. Slightly more expensive, but at least you have satisfied customers.
