NEW HUAWEI SMART PHONES

I have no words. This p40 lite is possibly the worst purchase I have ever made! I cannot access any of my important apps because of this Google play store ****! I can't access my FNB app which I use daily! Trying to access the desktop site is impossible because I'm permanently logged into the app. Which I now cannot access! So I'm completely *****ed with my FNB account. I can't access my Google maps which I use daily as I am a rep who drives around every day. How the hell am I supposed to do anything?? The mtn reps kindly left out the part that I won't be able to access most of the Google play store apps. Now I'm stuck with a phone I can't really do anything on? I can't even download my YouTube videos for offline viewing because of this nonesense. What am I supposed to do? Useless useless useless
