Questions about LogiLink USB A - A

I am a little confused. The illustrated packaging says 15m, but the description says 20m? Which is right?

actually, my delivery was supposed to be here today at noon. but it's now 16:38 and it's not arriving today either. if i had known, i would have gone by myself this morning and picked it up. Mon 01.07.2019 15:58 Registration of the consignment by the sender (data submission) 3030 Berne Head Office Swiss Post Tue 02.07.2019 07:40 Consignment has been sorted and forwarded 4620 Härkingen Parcel Centre Tue 02.07.2019 13:46 Item has been sorted for delivery 8520 Frauenfeld Parcel Centre. 13:46 and my parcel is still on the way instead of being here. i have already paid for it. the delivery date would have been today at 12 o'clock or by 1 o'clock. and not on wednesday. because now it is coming on wednesday. that means 1 day later. well, that gives a minus.
