Stupid, useless Huawei 8i Nova!!

I got my brand new Hauwei 8i Nova about 7 months ago as my friends said it is a great phone as I normally got myself an iphone as my first choice. Sad to say, the phone just freez up, unresponsive. I thought it was just a glitch and did not take the phone back in the 7 day return policy. The phone does this 5 to 7 times daily now!!!! I have wiped the phone, did al the updates, clear my open apps as was suggested but still this happens. I will not recommend a Huawei to anyone ever!!!!!!
