Lost email and left with no connection

I have migrated from ADSL to Fibre, firstly VUMA came to install the fibre box, then the modem was delivered yesterday.

I tried to connect and called technical to be told that the connection isn't active their side, to add a cherry on top my original email has been closed and ALL my emails is gone, this is UNACCEPTABLE, when I placed the order I requested that I keep my email and what do I get... NO EMAIL service all my information for the last two years is GONE with no warning or advice to back up emails, and I still have no connection!!!!
