Wont refund a faulty action camera

Bought a new Action camera from a dealer, After few months of battling to repair the camera and fault after fault. I requested a refund as I had replaced the faulty camera with a different working brand on holiday. <br> Once I returned back from my trip, I sent the camera in immediately and requested a refund, They would only replace the unit with another unit after a long pleading. I was not happy with this so I went to the store I purchased the unit from and they were happy to do the refund on the grounds they can get a refund from Navworld or replace it with a new unit for there store. <br> NavWorld first agreed with this on condition of a handling fee (which I agreed upon), then changed their mind after their regional manager was unhappy with the transaction. <br> <br> Im reporting that their action cameras are faulty and will give you head aches like you have never. While I was there trying to reason with them another client was also their with exact same complaint. <br> <br> Don't be taken for a ride by Garmin like I we did. I have lost all faith in all there products.
