I just got my PAC from Three via SMS, then signed up for a new contract with EE online. I worked at Phones4u when I was 18 and this process used to be an absolute nightmare. I dread to think, the amount of time I've spent on hold to networks to get a customer's PAC just so the sale didn't walk out the door.
No, I am not cut out for sales. I know this. I can't imagine me doing it either, but someone had to pay for my Marlboro Reds and hair bleach.
