Cellphone ordered

Ordered a cellphone according to the advertised on internet. The advertised phone have a 32 gig memory and 16 Meg camera. Battery life is of a very high standard. The phone competing with Samsung S10 and iPhone.

After one month received on 12 December a phone but it have only 8 gig memory and only 8 Meg rear camera. Battery hardly lasts for one day. This is totally not what they originally advertised.

Please could you help me with this problem.
