OneDayOnly - Zero Customer Service

Hi, I have never done this before but when you are so frustrated and just want to air your voice then this is the only thing I can think of. I received the wrong size item on 29 June. Since then I have sent 6 messages on the 'contact us' tool and never had one response. I don't know what to do and am so frustrated. There is absolutely no number anywhere so all one can do is write an email and it obvoice just goes into a dark void. FRUSTRATED!!!!

Has anyone else experienced this?Y
