NEED TO EMAIL AND NO EMAIL ADDRESSES

I am in arrears with my African Bank account and do not dispute this. I am not happy that they will only phone me and insist on me giving all my private details over the phone - if it actually is African Bank phoning me - I have no proof whatsoever. I refuse to give personal details over the phone to someone. I verified with my birth date and he told me this was not enough and I must give other information which I refused.<br> <br> in future I will only respond via email as I am unable to take constant calls during the day at work and I spend a good part of my evening driving home and then I have children to see to so I do not have time for lengthy calls. I have checked the African Bank website and they do not have any emails available at all to send an email to anyone - not even an information email address so have no idea how to get hold of someone other than having to phone which I cannot do. Please supply an email address for collections so an arrangement can be made that I am happy with and that I do not have to advertise all my personal details to a stranger over the phone.
