Nedbank Merchant machine not showing a transaction

Nedbank Merchant machine is not showing a transaction made on the 4/02/20260, a transaction of R18 000 made this past Wednesday 10h00 am, is only showing a transaction of R400 made the same day, I just recently purchased the machine on Tuesday however my excitement was cut short, even the client services can't pick it up, I used my money to offer my client a service because he swiped the card on my machine, now I am frustrated and stranded, my daughter's tertiary classes are commencing on Monday, I need my money
