Difficulty in contacting FNB by email

It now seems impossible to send an email to FNB - everything appears to need to be done via phone and the FNB app. Do FNB realise that some of us are quite elderly and the phone is not a media which we enjoy using - other than as a phone or for messaging ? I have a problem with renewing the lottery and after speaking to several people was asked to submit authorisation information via my phone. Sorry not on. Can someone from FNB tell me why I get the following message when trying to renew or play the lottery ? Your LOTTO, LOTTO Plus 1 purchase request was unsuccessful. - Invalid Nr Of Draws
