Thanks Alex, sounds like speaking from experience
. It seems outrageous to have to physically install a new line and a new master socket.
Unfortunately with Plusnet there are extra costs involved in a new line install. BT can however, do it for free - but with my experience with BT, they won't actually do it if they find a stopped line already at the property.
Today, Plusnet confirmed the line is stopped and said that only one order can happen at one time on the same line. They asked me to ask Vodafone to cancel whatever order Vodafone has on the line, in order for Plusnet to place a new order.
