Sorry. Yamimeal does not support changing in address after an order is placed. Customers can negotiate their situations and demands with Merchants via IM.
P/S: Regarding the issue of changing the delivery address while being offline, Yamimeal does not guarantee the replaced address for the delivery will be the final destination for the order placed.
1) Before placing an order, you can directly contact the merchant with the button located on the upper right corner of the store
2) After placing an order, you can view the order details under the current order and click to enter to contact the merchant
If you need further assistance, please feel free to submit your request to Yamimeal Care Team through our Help Center and we will contact you as soon as possible.
