I have used this service several times and I will probably use it again in the future but there is a lot they could do for improvement. The main problem for me is that they are not very reliable with the pick up. For example I was stuck at home a full day waiting for the carrier which never showed up. He came the day after he was supposed to pick up my parcel at 4 in the afternoo,this means I spent 2 full days at home( in my holidays) waiting and the most annoying part was,when I checked the status of my order it said the first day the collection wasn't possible because nobody was home which is a plain lie(even in the unprovable event I didn't hear the door they had a phone number). So very unprofessional by GLS.
