Perhaps try chatting to an iD adviser, using the online Live Chat service, ​@Gp2024. 

The customer advisers work until 8pm on weekdays - just tell the 24/7 chatbot you’d like to “talk to a person”. 

Hi ​@Gp2024 

Thanks for reaching out to us here on the community. 

We are sorry to hear you are experiencing issues with the service. 

Can you please provide the postcode for the area and the make/model of your handset?

SE1 9lf

EC1 1aa

it’s everywhere, the connoction has just massively deteriorated

Just on a whim I picked the 2nd postcode (SE24 9JY) and put it in here

https://www.three.co.uk/content/experience-fragments/threedigital/uk/en/site/mvno/network-status-checker/idmobile.html

And it states this:

We're fixing an issue in this area at the moment and aim to have things back up-and-running as soon as possible.

We're sorry for any disruption this may cause and will add any further updates here.

You can, if you decide, try the others.

Hi ​@Gp2024,

I have checked the postcodes and the only postcode I can’t see an issue at me4 3ju.

Unfortunately I can’t find the postcode EC1 1aa is this a new build?
