Hi @Jenia,
The staff here on the community will be on holiday until 29th now I'm afraid, the Christmas opening hours for the live chat and phone support teams can be found here.
Are you sure your TalkTalk service has gone live at your new home (did you get a text / email to confirm). Are you able to plug a landline phone into the line and call 17070 to confirm that the line is active and has the phone number you expect.
What do the light(s) show on your router when you connect it ?
Staff here will be able to pick this up, hopefully on 29th, if you still need their help.
