Stylo swift the overheating phone

I am so mad right now I am using Stylo swift. This is the most stupid phone I have ever used this phone keeps switching off time to time I have even lost count of how many times per day the phone has switched off even when it is not hot (overheating) then next thing after turning it on the network takes up to 10 Min to be fully restored. I wish I had know things about this phone before I bought it because then I wouldn't have wasted my money on this nonsense called phone
