Hi @Rusion ,
Are you able to log into the 'My Account' site, this will allow you to go to the service centre and do a test on your phone line, this will indicate if there is currently a fault on your line.
Also, if you have a landline phone can you check to see if that is working normally (i.e. you have dial tone and no noise on the line).
The staff on this forum won't be around until Monday now, so you may get faster support by using the live chat or phoning up over the weekend, however the staff on this forum will be able to help next week if you are still having problems.
For one of the TalkTalk OCE's on this forum to be able to look into this you will need to update your community profile to include your name, landline telephone number & alternative contact number. This will allow them to identify you, and they will then be able to help.
Don't post any personal details in this thread, just add them to your community profile.
