Makro Vanderbijlpark - Errors on Skyworth Android TV Box

Between 08/05/2020 and 09/05/2020 I bought 3 of these android boxes. All 3 started to give errors when I stream and I took 1 android box back to Makro and explained to them what happened and also printer out the errors to be attached to the documentation so that the department can understand exactly what errors I talk about. I received an SMS on 13/11/2020 stating that the unit is back at the store and ready for collection. When I got to the collections department I was told that the unit was only replaced with a new one. Penelope who assisted me on13/11/2020 was also the lady who did the booking of the device on 09/10/2020. I told her that I don't want the device back and would rather take a different make android box. She spoke to the department head and he stated that he is not willing to credit me the 3 android boxes so that I can take a different make as the Skyworth Android Box has been discontinued. It is not my problem that it has been discontinued but now I have to use these defective boxes and in total it has cost me R2547.00. This is really unacceptable.
