Makro service is so disappointing. They have no regard whatsoever for their customers.

I'm extremely disappointed with the level of service with Makro. I purchased a Inverter beginning of September with Makro online and the reason I bought it is to assist me during reduction which last for 5hours. I had it connected in my house after a week or so and the first day of it being connected, it worked perfectly fine. I had another load reduction again after some few days and the second time of it working during loadshedding, it worked for only one hour and then the battery switch behind the Inverter tripped . When I tried to flip the switch up again it just doesn't go on. I tried to a log the return online but I was struggling to log it because the app wasn't giving me the option of logging a return and I eventually called their customer number *** and they eventually assisted me to log a return. Makro then sent the courier guys to come and fetch the Inverter which took them forever to give us a response regarding the matter, until such time I called them to enquire about the return. The following day the sent the product back saying that the product must have fell that is why is not working. We sent the product back and told them that thing never fell to the floor and that it is the battery switch that just tripped from nowhere. Every time I call them I get different responses all the time and the last time I enquired they told me that they are rejecting my return because I used it in a way I was not supposed to use it ( I don't know which way is that because they are not being clear). I think they just looking for an excuse of not paying refund back they keep telling me that they will be returning the Inverter to me. Makro service just sucks.
