Shocking after sales support and terrible products

I purchased two Enertec 674S-red 12V 105AH batteries at the end of July 2023. My inverter was installed mid August 2023 so the batteries where only put to work then. At no stage during my purchase was I ever asked what the batteries were for, nor was I ever warned of their terrible life span. I decided on Enertec due to knowing someone with exactly the same set up as I had. They have used their batteries far more frequently than we do and had their's around 1 year when I purchased mine. I ran my inverter at maximum 8%, using a fan, TV, wifi and 2 led lamps for 2 hours during load shedding. Now I'm lucky to get 1 hour running nothing more than my wifi. The frustration is not only the fact that the batteries lasted nothing more than 6/7 months but the disgusting after sells Enertec Johannesburg supp**** me. To get ahold of anyone is hard enough but eventually got put through to Kenny. I explained the situation and Kenny asked if I would bring the batteries through, I told Kenny they are 45min away from my house and I need to know when I arrive something can and will be done. I took the batteries through, parked near the door and not one person asked if I needed assistance or help just stared blankly. After getting the batteries inside I was quickly told I'm wasting my time as these batteries last nothing more than 3 months with load shedding stages 4/5 or 6 and they won't change the units, they will check them and let me know in 3/4 working days as to what is wrong with them. I asked the extremely abrupt employee how this was possible and why no one warned me of the batteries life span. He abruptly stated I can research and educate myself they are all like that, to this I responded that I come to a battery place to buy batteries and have your experience and expertise lead the way. I feel it is well known Enertec supply inferior quality products and services, I would strongly suggest using other suppliers other than Enertec as all they want is your money.
