Thanks for coming back to us on this one and confirming the issues you're having with WiFi.
Our new WiFi Max service allows you to have up to 3 pods. Whilst the 1st pod can be requested, a second and third pod can only be ordered after diagnostics have been completed and we determine that a Pod is the correct fix for the connection issue. The pods can only be sent out one at a time too.
It's worth having a look at the service as a whole here and please note that unless you're on a 1GB speed or a Volt package then there is a charge of £8 per month.
Once you've had a look at the above link, if you want to go ahead we will need to confirm some information with you to get that first pod sent out.
I have sent you a private message regarding this. Just click on the little plum envelope at the top right-hand side of the page to access your inbox.
