I am trying to register with the PRTB online, I have answered all their questions, apart from the question asking for the mobile phone numbers of my tenants which amazingly turns out to be a compulsory question!!. Now my tenants don't have mobile phones, but in order for me to complete the online form, they don't appear to have that option. Any suggestions, how do I register?? I have sent a query to them, asking how can I pay the registration fee as I am unable to complete the online form, but the feedback on this site tell me I can be waiting months for a reply which will go way beyond their 30 day deadline. Will the PRTB provide my tenants with mobile phones and net provider contracts I wonder. In this day and age of expenses it is highly irregular never mind an invasion of privacy to insist on mobile phone numbers. yes most people in Ireland have mobile phones, but last time I was there it wasn't illegal not to have one.
