One of the most useless suppliers out there. I have had a problem with the app for our smart fridge after about 2 months of owning it it happened after a update. I have been ringing them for around 1 year now to get it fixed. Evey times its ill send that info to support who designs the app or whats the problem again. So sick of them and there bull s**t excuses they have no idea how to fix anything and just do not care STAY AWAY FROM ANYTHING SAMSUNG if it stops working they will NEVER help you. I wish i could give a -10 stars but i can't so i give 1 witch they do not even deserve.
