Stay away from Goc Energy 93 Elsecar street Kya Sand Randburg

I've recently purchase four gel batteries for my inverter. After the first loadshedding I discover they sold someone old batteries to me as new since the new batteries did not last as long as my two year old batteries. After four days they replace batteries with the same result. I paid a company to verified that the batteries they replaced need to be replaced. So they sell only second hand batteries as new. Received R 4000 back. Now I am battling to get the difference back what is R 4000 from R 8000. They did not return my better batteries what they took and most probably sold to someone else as they done to me.
