PSTN Cease

Hi All! Its been a long time since i posted on here!

My question is this .... i am making the move from plusnet to the Sky Max package. I have received the router and have set up and getting a connection that is very up and down at the min (only been connected since sat) but thats a different issue. I have since emailed plusnet and advised them to cancel at their end.

Today though i have received four emails telling me that a cancellation order (aka PSTN cease) has been placed on my telephone line. Is this normal or should i contact Sky, Plusnet or BT asap?

I think it's normal looking at my line order it says provide one LLU and cease one PSTN 5 days later
