I had my O2 router sent out as im a new customer, they attempted twice last week when I was out but never left cards, only got a text day before first attempt just saying a parcel would be delivered next day, no mention of courier name, none of who parcel was from so I ignored it thinking it was a junk text.
When the person came round today it was a woman who looked in her late 50's wearing casual clothes and no delivery van(think it was a car) with just a id card which I coudlnt see,
When I opened door she just handed to me, I said thanks she said "it yours" I said "yes" and she just walked off.
No forms to sign or anything.
I just found this strange as I had no idea who the couriers were.
