I purchased a pressure cooker about 18 months ago using credit card rewards points and have had had issues almost from the start with it not working correctly (has touch buttons and they won't press). The manufacturer has had it repaired twice over a 12 month period replacing circuit board and the buttons. After the last time it was fixed, it lasted about 2 weeks and had the same issue again. Before the last repair, I asked for either a replacement or a refund and they said it would need to be assessed by the repairer first. In the end they 'fixed' it.
Now it has stopped working again and they are wanting me to take it back to the same place to (presumably) have another repair that will send me back again in a few months! I feel like I am going round in circles!
Now my question is, am I able to go to the credit card rewards program provider (as the 'retailer') and seek remedy for a major failure under the ACL?
Yes you should treat the rewards store as the retailer and seek a refund of points for a major failure under the ACL.
