Shockingly Poor Client Service !!

I purchased a couch and upon delivery discovered that it was too big for my room. I called to log a return on Monday this week. On Tuesday upon following up, I was informed that the call was logged and documents were requested which I sent. I have tried calling on Wednesday and Thursday for feedback from Nosithembiso who does not believe in returning her calls which is extremely unprofessional. When escalated to her senior, after no response to plus minus 5 to 6 messages left, I was informed that the return was logged with the courier. I requested for feedback as to an expected date of collection or I would escalate this further. Both the client service liaison and her senior obviously don't care as to date I have not received any response or feedback. The service is shocking to say the least. It's like dealing with a brick wall!! It's just disrespectful and rude for client service staff to behave in such an unprofessional manner.
