I brought my iphone 12 mini for replacing the battery, to Coolblue. While they repair my battery they broke my side button and instead of fixing the button they gave me a "new" iPhone 12 mini. This phone was overheating and getting stuck from time to time but I tried to be patient. After 6 months the wifi, Bluetooth, torch wasn't working the battery was even worse than before I changed it and it was constantly overheating. After some digging I found out that this was a refurbished phone and when I contacted them they told me that the repair was out of warranty. What a great Service Coolblue, thank you very much!
