Bad experience with the Nedbank Pocket POS machine & poor customer service from the Merchant Department

Recently got the Nedbank Pocket POS machine and to say I'm disappointed about the service is an understatement! I literally have to call the bank after every transaction to request an escalation for the funds to be released which is also not helpful, they still take forever to be released. I'm currently waiting for funds from Wednesday and Friday's transactions to reflect. As a result, my 28th debit orders have bounced back. This whole experience just made me question the banks competency. I called in today to follow up and requested to speak to the manager and she was also of no assistance and put the blame on the Sales Department which was closed. How can the department leave an issue unattended for 3 days, they do not even advice on the reason the funds are held back. I'm seriously considering moving my personal and business accounts elsewhere because this is unacceptable!
