ABSA Online Business Banking

At the end of April I sent a query to our banker regarding our business account that we are unable to use our internet banking as we need to validate the account. Message upon message and email upon email we have followed up and to date the matter has not been dealt with. We have contact the callcentre who also escalated the enquiry. We have gone into to our closest ABSA branch to be told we have to deal with our banker? We have forwarded latest proof of residence, certified ID. What is a person to do to have this matter attended to?
