Hello I placed an order for three items a few days ago. Today I received an email saying that one of the items cannot be produced in the material I selected, and that my account had been credited for that item. However, I would like to change the selected material so that all three items are shipped together. I do not want to have place an other order an pay for two lots of shipping. I have emailed, tweeted and tried Live Chat but haven't gotten a response yet. Can someone help me, please?
