If the address isn't showing on the system then they will probably send out someone to have a look at your property to see if it is a) serviceable and b) residential. This is in turn fed back to the Housefile people who *should* amend the database. However due to reorganisation and everything now being centralized, we've found there was a delay and upto quite recent, two weeks was the timescale
I can't imagine that things will stay like this for long and it should be back to normal soon'ish but I can imgaine how frustrated you must feel. The person you speak to should be able to ring through and see how things are progressing and hopefully be able to give you good news. I would probably wait till Tuesday and then give it a another go.
