We have been waiting for a phone number to migrate...

We have been waiting for a phone number to migrate for 40 days.
The operators we speak with do not know anything about it, but they tell us that they will call us back soon ... but of course nobody gets hurt.
They also asked us to send (after we had already sent it 30 days ago!) A PEC with the signed documents.
At the moment we are very disappointed.
Of course we hope to change this review in the coming days (but guys call us and follow our migration, because you just do not go!).
We look forward.
