Yes thankyou. Eventually got to speak to somebody who told us there was an "outage" and that it would be resolved by the next day: which it was.
A home phone line fault is unique as it is not possible to use '150' as you can for all other service issues. Using a mobile for calls with very long wait times incurs costs which can be significant and if it PAYG as we have funds can run out before your call is answered. VM needs to find a different way to deal with this or have a reimbursement process. I have also written to the complaints team.
