When was you told this? When you signed up or recently?
Do you have any documentation that tells you what you are supposed to get?
If you have had Infinity 1 for 18 months, up to 40/2 is what you are on. Somewhere there is a page on the web site to order an upgrade to "up to 40/10" at no extra cost. It is not an automatic upgrade, you have to order it and it results in a further 12 months contract.
Edit come the morning - here is the page where you can start to order the upgrade.
So guys, how do I insist on improving this 40/2 profile? I've tried contacting BT Helpdesk... useless... unbelievable!!
When I first order Infinity I was told that as my ADSL was <15Mb it would not be 'Infinity' but 'Broadband with fibre'!! I wonder if this is linked to my current problem?
If you are on faster total broadband then the upload for that is 2mbps, so you are getting what you should be. You would have to persuade them to upgrade you to Infinity if you wanted a bit more upload.
Thanks john46, I submitted a case yesterday and wait with baited breath 😉
