I ordered a sim only from phone car phone warehouse and several days later it had still not arrived. I phoned to chase and they said there was a warehouse problem but it will now come out. Again, days followed and nothing had turned up, bearing in mind this was only a SIM card not a £400 pound phone, it's not rocket science posted first class post! Deciding this was not worth pursuing I phoned and said let's forget it and thought this would be the end of it. But then then letters arrived saying I hadn't paid my bill followed by debt collectors letters. Fortunately, the lady at the debt collectors I spoke to must have believed me because nothing else followed. A true story.
