Used Quidco to get cashback otherwise I would've gone to Carphone Warehouse. My current provider couldn't match the deal so I chose this site. Order went through ok but it allowed me to choose a different delivery address to my billing address. This resulted in a problem and my phone didn't arrive. On the day it was meant to arrive I received emails and text messages saying to contact them and resolve the issue. I rang the number from my phone which cost me to resolve issue. Helpful enough, changed the address and said it should be delivered. 4 days later, no phone, no email. Called again at my expense, waited for over 10 minutes on hold. Spoke to someone and the phone should delivered next week. Hopefully the cashback is more than it cost me in calls but it wasn't a smooth transaction
