Prestige cold called me saying they worked with O2 (current provider) and wanted to see if I’d be interested in upgrade. A 10-minute conversation quickly turned into a 4 hour phone call going back and forth with Prestige, Plan.com and my current provider. I am totally at fault for being sucked in, but upon learning more about them they refused to cancel my contract and demanded a £330 fee. Something that has never been a problem for me, my phone, suddenly became an enormous headache. If this company call you, put the phone down immediately. You only have to watch their promotional video on their website to see they care more about money and sales than they do about customers.
