Urgent need for credit card terminals and bad service

I have an Absa business bank account for almost 20 years and been requesting additional credit card machines for the past 2 weeks. The gentleman assisting keep a making false promises to arrange delivery of them but seems like has actually did nothing. I have lost a lot of business due to this *********** and unprofessional service from some staff. I need the new terminals like yesterday but don’t know which way to turn or who to contact. Can someone assist ? Anybody know which other bank can provide a faster service in which case I am happy to close all My Absa accounts and Mine Elsewhere
