CooliCool is a scam and they are not to be trusted! I bought a smartphone from their store and also I paid extra money for warranty. I received my phone and it didn't seem like there was anything wrong with it, it worked pretty fine, but only for two months. Then it broke and I contacted CooliCool and asked them to fix it, but they asked me to pay for the repair service. I told them that I had a warranty, but they replied that I could not use that in my case. I demanded some reasonable explanation but received no reply. These people are cheaters! They sold me a defective phone, and refused to fix or replace that. These people are ready to work only for money, they don't honor their own promises. Stay away!
