Useless products and service

So I bought a Fitbit Versa Lite through FNB end May 2020. Received the watch Beginning of July screen went dead and watch stopped working for the first time October 2020 this mean the watch worth R3500.00 only lasted 4 months before breaking. Got in contact with Fitbit they sent me a replacement no problem. Alright no problem. Fast forward another 4 month same story screen dies watch stops working. This is now end Feb 2021. This time we have to send the watch to Fitbit in the Netherlands wait almost a month and then we receive a new watch. Now it is Mid July which means it is not even 4 months later and once again the watch is broken exact same issue screen went dead next morning the alarm still went off with black screen and next moment there is nothing. Get in contact with Fitbit they just come back and say sorry not a valid warranty claim, here is a discount on a new watch. Please tell me why I would even consider buying another watch if I know I am just wasting my money and will have to buy another new watch in a years time?????? Now I just feel like there is obviously something wrong with the Versa lite as the watch just does not seem to work for more than 4 months, this is obviously a factory fault on the item and for a big company like Fitbit to just wait out peoples warranties and then just say sorry not my problem is very irritating and unprofessional. People pay a lot of money for these watches and to spend R3500.00 for a watch for a year is absolutely crazy I will definitely not buy Fitbit ever again and I will make a point of telling everyone I know to not waist their money on this brand as they are over priced and the products do not last at all.
