Hi @Nicdonks, welcome to the community.
While it could be argued that a vibration isn’t a true massage (by hand), the massage industry uses vibration, poking and prodding, warm stones, hands, manipulating muscles etc as part of a massage.
Unfortunately since you didn’t like the product after its use is classed as a ‘change in mind’ under the Australian Consumer Law. With change of minds, a retailer can chose what its policy is in relation to a product which is returned and doesn’t have any faults. In this case, Coles is in it rights to refuse a refund or to take the product back for any other remedies. It can also nominate its own change of mind policy.
Notwithstanding this, Coles has a Try It. Love it. Or Your Money Back guarantee which states if one is dissatisfied with a product…
In accordance with our “Try It. Love it. Or Your Money Back.” guarantee, we encourage our customers to return the product, empty packaging or receipt of any Coles product they weren’t happy with, for a refund or replacement. This guarantee also applies to fresh produce and Delicatessen items.
I have a branded product I’m unsatisfied with, how can I get a refund or replacement? Please return to your local store with your receipt and the product if possible and our friendly team will assist you at the Customer Service Desk.
I can’t find details of what products the ‘guarantee’ applies to but it may be worth returning to store and quoting this when you try and return the food massager again. It is possible you may get the same response as before…which they have a right to do.,but it may be worth asking too see if there is a different response.
