2.5 years ago I purchased BT business infinity as wanted to move a business to new property.......they still have not sorted the fault to get sustainable lines and are now saying to replace the old copper lines, that do not work properly I have to pay for a new line....yeah right! I have had to speak to no less that 17 individual people, as they like to talk and not email unless pressed....of course...as they do not like written evidence........and even now new routers and engineers popping in unbooked and leaving without so much as a good bye...they have no idea how to run a corporate....... ***! Inept and pathetic you are BT, all of you thieving pratts!
