These people cold called my work phone. They were vague about who they are (sales pitch awful and with no enthusiasm). I had to press to get more info than "challenger" - even then I only got that they were based in the North West. They stated they were "Platinum O2 Partners". When I said we have a partner of choice, they hung up on me. Incredibly rude. If that's how they try to get business, I consider myself lucky i'm not in contract with them.
