On my Gear Fit2 Pro one of the wrist bands came off while I was running. The metal insert into the band silicone that keeps it attached to the watch is a very poorly designed. This is when I decided to send it for repairs being under warranty and I was directed to Futuretel by Samsung.
Customer service is one of the worst I ever dealt with. After waiting almost 3 weeks I was told that the liquid got inside and damaged the board and the wrist band breaking was due to physical damage and is not covered by the warranty. I was asked $338 for repairs and $35 dollars for the shipping.
I explained them that according to Samsung website the device is made to withstand liquids. The only liquid that came in contact with was my sweat. I refused to pay and called Samsung. Samsung plays the same record and refuses to cover the warranty claiming liquid damage. If the device is made to swim and it supposed to last up to 5 ATM how liquid got inside??? Spend numerous hours on the phone with them and got nowhere.
Now a couple of hundred dollars later I m without a fitness device, and more frustrated than ever.

This is what classifies this product under the false Performance Claim and Misleading Advertising and in Canada there is a law for this under the Competition Act.
"At the federal level, the Competition Act is the primary legislation governing advertising and marketing. The Competition Act contains both general criminal and civil misleading advertising provisions, which prohibit false or misleading representations made to the public to promote a product or any business interest."
Anybody knows a good lawyer?
