Nokia C10 nonsense

I have always trusted Nokia when it comes to cellphones but this time am extremely disappointed, I bought Nokia C10 last week Friday the very same day phone started acting up, I miss called every day while I have the phone with me, phone rings but the screen doesn't show anything, I miss important calls coz of this nonsense of a phone, it's super slow,i regret buying this phone and will never buy any Nokia brand ever again, what a waste of money I don't even have,it's just big for nothing
