Return Not Processed

They're telling me accessories are missing from my return. First of all, I never used the item because I didn't like the material so I know nothing could have fallen out from the order. Secondly, they don't even specify what they mean by accessories, so I don't even know what they say is missing. But the worst of all, they don't have a contact number, so I can't even get hold of them to clarify the issue because the email communication just went dead. Return MRRN-RZ5RP-G765
