Totally disappointed

Good day. I purchased a mini UPS on takealot on the 15th of Dec 2022, it was delivered on Sat, 17th of Dec 2022. I plugged it in and let it charge to full and when the power went off for loadshedding so did the UPS... clearly a faulty device. I logged a return and exchange on the morning of the 18th of Dec 2022. The tracking tells me that I have to wait 4 days for the faulty one to be collected and a new one delivered... so it will only arrive on the 21st of Dec 2022. I understand that this is the busy season but are exchanges of faulty products not a priority? I tried to get help on the takealot facebook page but nothing transpired (no help recieved) and I call your call centre to only waste all my airtime because you hold on forever.
