Samsung Galaxy S8+ not as advertised

I have just upgraded to a Samsung Galaxy S8+ (SM-G955F) Coral Blue from Vodacom. I received the handset yesterday but however I am disappointed about a few things:

1. My phone only allows me to insert one sim card. I thought it should be able to optionally take a second sim card in the memory card slot? I do not like to carry two phones around, so one of the reasons I bought the Samsung S8+ was specifically for this feature.

2. It does not have FM Radio. Can't I listen to my favourite radio stations without having to install apps that will use my data to stream the radio? Do I have to get the phone rooted just so it can work? The phone obviously has a chip inside for radio functionality.

3. Where is the wireless Charger? I thought that this was supposed to be included in the package as well. I only received the phone, AKG earphones, Charger adapter and cable, Pin to open sim card slot, and two other USB connectors.

4. How do I claim the R5000 Flight Voucher? I did not get the push notification when I activated my phone.

I hope that you find the above complaints in order and that it is resolved to my satisfaction ASAP. Right now I feel like I am not getting what has been advertised to me. Please give me what has been advertised to me or take your phone and refund me.

Awaiting for your response in this matter...

Thank you
