Well, Hooray!, what a surprise.
BT called, told me they would install me on BT Infinity for free, and I would remain on my current tarrif....so no change in my average bill.
I agreed and have been using it for a few days and it seem to run aound 36.6 Mb/s download and 7.2 Mb/s upload, which is fantastic compared to my maximum of 3 to 4 Mb/s download. Of course it seems some of the websites I use are a bit slow.
BT assure me that my speed will not vary very much for those speeds -- and I have checked several times using an independent speed checker.
Could it be I did the right thing..............for once?
