Disgusting service. Give customer deffective equipment

I once again have to resort to Hello Peter go help with the same company. Since we have been thrown into Stage 6 loadhsedding, i have been forced to use a UPS system to have internet connectivity (this UPS i got as part of my contract with RSAWEB). I opened the given UPS for the first time yesterday (22 Feb 25) and the UPS worked for 10 minutes and then stopped. I tried it again today 23/2 after charging it for over 4 hours and it still didnt work during loadshedding. I reached out to the technically support of RSAWEB who told me that the UPS is deffective!! What nonsense. Why would they give customers deffective equipment, and apparently according to the technichoan, Thulani, he will log it for repairs and i will have to pay R390 for this.
