I would have thought Plusnet would accept you on the 76/19.5 product on those figures. Was it just their online checker you have been looking at?
Many long-term users are thinking of leaving Plusnet by the way. I've only been there since Feb 2012 but for two and a half years from then have been strongly recommending them. Only a couple of times in the next three months, and not at all now.
Almost certain to leave within a month.
There are ongoing problems with their infrastructure, and the BT-appointed in December 2103 CEO has, after a few earlier downgrades to CS, now really wrecked it.
I don't want to be with a company that can mess its customers around the way they now are being.
The indispensable man or woman passes from the scene, and what happens next is more or less the same thing as was happening before.
