In that case, I suggest you call them tomorrow and ask them to explain your options. Don't commit to anything but take careful note of what they say, and let us know.
I did phone them this afternoon, my only choice seems to be migrate to EE to keep a home phone, or part fibre broadband only with Plusnet. Or look elsewhere I suppose. I have always been happy with Plusnet and I don't like change for change sake.
I thought that may be what they would say,and to be honest, for you, it is probably the best option to move to EE. If you stayed with PN for 'part fibre', you would need to arrange a phone service with another (VOIP) supplier.
