Signing agreements

[Vikki92]

Right can someone help me here. I ordered a new phone on Thursday I need to sign my credit agreement but it won't let me do this until I link my mobile id to my current sky tv account. The problem is when I'm trying to do this it keeps saying the details I'm adding are wrong. They absolutely are not when I ordered the phone I paid an upfront cost off my bank card and set my payments up to come out of said bank account. I'm entering them details and it keeps coming up saying details incorrect. I've tried to contact anyone at sky multiple times to no avail was told to wait 24 hrs that didn't work and everyone else's is just repeating the same thing link account so I can sign agreement. When I click on the sign agreement part on my account it just goes to a blank page with the word complete in the top left hand corner. I'm about to rip my hair out and just cancel the stupid thing and order from elsewhere. Can anyone help me out here

Your mobile account doesn't link to your TV account as you need to link it to your Sky ID so is this what you are trying to do ?
