AliExpress complaint: Return Address

We are returning a coffee maker to AliExpress Seluna store as a result of a resolved dispute. The return address provided by the seller is different from the address we had received the package from. Return shipment means delivering the purchase back to the shipping point.
Second, the return address provided by the seller does not exist in the Canada Post address database. The address googles up with errors. We are not sure if the item shipped to this address will reach the seller and consequently the refund is issued.
Would you assist us in convincing the seller to accept the return shipment at the original shipping point?
The shipping point address is: UCL Co LTD, Toronto Returns Gateway CR, Dixie Road Mississauga ON M0R 4Y0.
The return address provided by seller reads: Li Junwei 18503055832 China guang dong sheng shen zhen shi long gang qu baimenqian gongyequ 2dong 3lou E3CN 518114 shen zhen shi guang dong sheng.
