My parcel with tracking number RG016007443CN shows it was delivered in Sweden but it was supposed to be delivered in South Africa

Hi,
I placed this order from a seller via DHgate & it should have been delivered to my address 31 Archer Drive, Cheswick Green, Solihull, B90 4LG, UK, however it was delivered on 11th June via Royal Mail to a wrong address in UK, the seller has closed his store more than 2 weeks ago & I can not contact him by any means, I appreciate if you can help, at least I want to know if he has given you my address & accordingly it is the fault of Royal mail to deliver the parcel to a wrong address, or the seller gave you a wrong address & in that case, I can get refunded by DHgate.
Regards

Hello,
I have put the wrong zip code (63111 instead of 63110) and the parcel is already delivered to the wrong address.
How can we reship it to the right address?
