I also had a response after emailing -

"Your words regarding Honor Oak Park station on are not lost on us we have every sympathy with the passengers and members of staff who are put under pressure and stress due to ticket machines being out of action.

At present I have no date when the machine will be up and running. We have had a series of vandalism attacks across the network over the last couple of months and almost all have been on our quick ticket machines. Please let me assure you that we are aware of the urgency of getting these machines working again and every effort is being taken to get them repaired.

We are hoping that Honor Oak park will be running as normal in the next couple of weeks.

Thank you for your continued patience and taking the time to contact us"
