One Day Only Product refund poor customer service

I made an online purchase from One Day Only on the 6th of August 2020 (order nr: ***). The product was delivered on the 18th of August 2020. Upon recieving my order, of which bluetooth earphones was part of it, I discovered that the left earphone was not working.

I contacted One Day Only via their contact email service. Response was swiftly in telling me what to do and how to return the product. This is where the poor service started. After now already contacting One Day only on several occasions, emailing the contact services as well as their operators (Nastassja D, Mishkah S, Armand B, Nicky de Kock, Brandon L I still have no clarity on whether they recieved the item that I returned, whether I will be refunded with the items value ir whether I will recieve a new product. There has been no communication since the product has been picked up by the courier.

I find this extremely poor and for the near future I will not be making use of the One Day Only shopping experience, and will rather use other platforms similar to this where the customer service is excellent.
