Incorrect E Mail address

I have a Woolworths store card and have opted to have my monthly statement E Mailed (who uses snail mail today) I have been trying to have the statement E Mailed for approx one year Whilst the call centre staff are helpful enough and even acknowledge that Woolworths have an incorrect address for me and some of them offer to correct it . I still do not receive the statement The only way I can receive it is to request call centre staff to E Mail Sometimes they also use the incorrect address so I have to repeat my call The mind boggles that an organisation the size of Woolworths can not achieve a simple task such as amending their records to9 reflect a correct E Mail address
