Cannot return faulty product, will not return as customer

I have used OneDayOnly for over 7 years. I have always found it uncomfortable that they don't have a contact number as I prefer to resolve issues telephonically. This became very apparent when a recent clothing item I received arrived with a hole. I tried to log a return on the website, from every single one of my 5 devices, and repeatedly got a "technical error occured". I then tried to log a support ticket, and got another "cannot process this request at this time" error. I have since then sent multiple emails to their ***, with proof of my statement above, and received no feedback. Effectively, I have thrown R250 to the wind, paying for a faulty product I cannot exchange. I vow to never use ODO again, and pay a small premium for customer service.
