PocketPOS software defect - no support from Nedbank.

My wife, who has a business account with Nedbank, paid R1300 for a PocketPOS Credit Card transaction device for her business. Two days ago, it failed with the message ** System Tampered **. I did a quick search on the internet and found that this is a common problem on these devices caused by a software defect. My wife contacted Nedbank service centre and was told that indeed it is a software problem - the device needs to be replaced, but since it is past the 6 month warranty period (we have had it for 10 months), she will have to purchase a new device. This is totally unacceptable! Really disappointed in a bank that is supposed to be "value-driven" - it seems that profit is the only value that drives them.
