Unsatisfactory service , poor Store manager interaction , disregard for customer satisfaction

I purchased a Skullcandy Hesh 3 bluetooth headphones on the 3 April 2021 and have had to return them to the Cape Gate Makro on the 13 April 2021. The left "U" arm over the speaker broke this morning after I put them on. The fight I had to go through firstly to actually be served was unacceptable The runaround by Makro Cape Gate is beyond believe . Firstly the product was returned with in the 14 days period in its original packaging , I get told the arm snapped due to customer abuse by a salesman that the returns counter staff had checked with on the floor after iI raised the question has the salesman on the floor had plastic injection or rotary molding experience or plastic engineering qualifications to make such a assessment , then they back track on that statement saying they are not qualified to assess the product they are just the "reseller" poor excuse , then they say it is not in the original packaging because the arm snapped and that is not the way it came but the headphones were returned in the original box with all the cables which had not been used as yet . I did managed to get the store manager come down and to be told sorry we just sell the product and cant help you it needs to be sent off to the supplier (whom I have contacted as well). The Store managers attitude was one of disrespect for me the consumer, he was very pre-occupied with having to be else where and from what I over heard it was a zoom meeting . Now I ask you what is more important your customers or a zoom meeting. The line coming into the returns section of the Cape Gate store was longer than the line for people to enter your store to buy. After our economy has taken a downward turn I can not understand how your Staff which extends from the Store manger to the counter staff can be so arrogant as the old saying goes " a fish rots from the head down". I think you need to look at your management team and get them into some customer service courses quickly. I am going to take this further if this is not resolved . I am not waiting the 21 days to have this returned to the supplier and back again . We have technology available nowadays to shorten this process.
