Voda landline suddenly becomes "Invalid number" / "not available" to Sky mobile AND landline callers

[cjpresy64]

I moved b/band and landline from Sky to Voda in June 22. Surprisingly everything went smoothly and have had no problems with either service until recently.

At some point in December (I think - as we don't get many calls on landline) my number became "invalid" to Sky mobile caller (which I and my wife are) or "unavailable" or similar to Sky landline callers (which my elderly parents and Aunt are). My dad actually alerted me just before Christmas that he couldn't get through to the landline.

Since then I've had several unsuccessful chats, calls etc with assorted people at Voda trying to sort it. I've also spoken to Sky who say that there's nothing they have done or can do to make this happen. I am able to make outgoing calls and can receive calls from other mobile and landline providers!!

Is it possible that some "upgrade" in November/December could have caused this ?

thanks @cjpresy64 for confirming. Which provider did you transfer your landline number from?

Hi @twok 

I transferred in from Sky.

I had a problem for a couple days with the port because somebody (I think at Sky) hadn't done something that should have been done. Can't remember exactly what though.

I've no experience with NOW.

I know they're a subsidiary of Sky but how much of their operations overlap ?
