I cannot believe the quoted fees on repairs

I am disappointed.<br> <br> I tried to check all my registered products and found out they are not on Samsung account page. I booked in 3 mobile phones and quotations received are scary! The first mobile I accept the quote with the pricing as it is the screen.The tablet has been repaired 3 times in less than 2 years already for the same problem (Not charging) by Samsung and it is still under warranty as registered on the website but to my surprise none of my 5 products are under my profile! Who deleted the information as some of the mobiles are still under warranty?I have been with Samsung from the D range and that is many years ago and this upsets Me! What happened to checking the repair history of the gadget before quoting ridiculous prices?<br> <br> The issue with the other mobile is the main board that is not working and the mobile is less than a year old , were is the warranty for this mobile? Can someone attend to this? I have had my dealings with Samsung in the past and they were smooth , and with this , I might consider leaving Samsung for good!
