Nokia still in the 90s stick to your 3310

Bought a brand new Nokia C30 from pep. After 2 months the 6000mah battery started lasting only 1 day. I booked it in at the Store where I bought it . It's been 2 weeks and still Don't have my phone back . Not only are Nokia phones faulty they also take forever to repair the device . I will never buy a Nokia ever again
