Useless service in gateway Clicks

Purchased a tony and guy hair dryer less than 6 months ago..which has a 5 year warranty..the hair dryer was intimitent working and I went to advise the issue to the manager ..she refused to exchange the device ..I had advised her the device was still under 6months and as per CPA I am entitled to a new device or a refund..she advised the unit must be broken completely for her to take it in ..she did not want to assist me in other way..as I advised the issue was intermittent. Cashiers in the store were not willing to assist me either...absolute terrible service ...they chase customers away so they don't have to do their job ...
