Buffalo logistics cooperates with China Dealz ****med me

Buffalo logistics in association with China Dealz ****med me .

I started by ordering an iPhone 7 128gb from China Dealz, I paid and they said that I would add the delivery fee, I did add it and they gave me the tracking code from Buffalo logistics. The day I placed the order was October 10th and today is October 31st, but there is not in my hands. I started suspecting that there is something wrong, when I track the parcel it says "international shipping" for a whole week it writes like this on Saturday it changed to say it's on JHB I waited and said I'm still waiting it said delivered but I didn't get a notification saying I must come to collect. when I text Buffalo logistics it says the parcel i delivered and received when i asked that it was delivered to whom they said i must ask supplier (China Dealz) for such information i texted china dealz several times and I got no response
