Lack of customer ethics and passing the buck

Vodashop Galleria finally gave me a call after my posting on Hello Peter to collect the Sony device (watch), collected on Sunday 5th July charged devise Monday and tried to use on Tuesday, to find the device is not working, went to another Vodashop for assistance and was advised that the devise is non operational and should be exchanged from the Vodashop that had done my upgrade. Called Vodashop 07-07-2015 was told they will contact me on 08-07-2015 and was told i should understand that the devise is a gift and not a product i am paying for, 15h00 no call from shop, I called the shop at 15h00 with my first call being dropped like usual, I informed them of my problem and was being given the suppliers contact details for me to call them to sort out defective unit. The store will not even arrange for collection due to the distance I need to travel to drop of the unit, nor does the store keep to their promises, nor do they care about the customer once they have been paid, I was told i will now have to wait for the devise to be sent to the supplier and the supplier will decide if the device needs to be replaced (SONY), whatever happen to our rights under the CPA act? to fair treatment
