Shocking Customer Service For Returns

Some of the most shocking customer service I have ever (not) received. I returned a product over a month ago, and received no update on the status of the return. After repeatedly requesting updates and not getting feedback, I contacted the merchant directly, and found out the product was never even sent to them for return. They've now managed to sully the name of the merchant, waste over a month, and leave me without a refund or replacement. I have still not received any response, despite repeated attempts to contact the returns team.
