False Advertising for the Samsung S8+...?

I bought my Samsung S8+ about 5 months ago, I paid cash for my phone. When purchasing I was advertised that the phone is water proof and dust proof. I read the manual which also says so.

I went to Mountain Sanctuary Park on Monday and we spent some time in the pool, took some photos, my phone only got splashed with water it never even go under the water and it stopped working.

When I called the samsung customer service team 2 times I got 2 different excuses.... 1. It's not guaranteed that it's water proof. 2. It's water proof only in fresh water.

The manual says 1.5m and blah blah blah. This us false advertising. It's either water proof or not. It cannot be waterwaterproof at your own risk! +/-R18 000.00 for a phone and you cant guarentee thats the phone is waterproof! And you are advertising that it is water proof that is not fair to your customers Samsung...we trust that you have tested anmyour product before selling it.

I watched videos on You Tube demonstrating the phone IN water and nothing happened to It, my phone got splashed with water and is not working!

You are a bunch of *****! Please sort my issue out I'm highly annoyed!
