Disgusting customer service from Tamara

My husband purchased a 40000mAh Portable Power Bank With USB A, C & Micro Charging Ports which we received on the 1st April 2023. We then returned the item on the 14th June MRRN-SA 4NQ- N6YA. The reason for the returning the item is because one of the charging cables stopped working. We received a green colored item. Today my husband receives a call from a lady called Tamara from the client services department. She gave us nothing but bad service. She basically accused us of sending an item bought somewhere else to takealot because the colour of the item on your app shows red and we received a green one. Why would we do such a thing?? The colour did not matter to us. When we received the item all we wanted was for it to do its job. Which it did till it stopped working therefore we returned the item. We are not ******* as Tamara made us look like. When we tried explaining and all she could say was NO. Is this how clients from Takealot should be treated. We have our purchased several items from takealot and this type of treatment is really appalling. We asked for a manager and was told that they dont take calls. She could not even give us the name of the manager. She refused to give us her surname. This type of questions that she was asking us was really not necessary. What we got from Takealot and what we returned are the same thing. She continually inainuated that we were lying. Telling us that we took an item that incorrect and used it and now we are returning it, just because of a colour....If that is the case then it means that Takealot sent us a wrong item which we didnt see as incorrect because it worked. We have a right to return something that is not working. If this is how the rest of your client services department treats clients then you guys will lose a lot of clients. Tamara did not deal with this situation in the correct manner. We would like a call from a manager.
