Greetings, 2 years ago I bought a back up system from solarway suppliers Address: 162 Barry Hertzog Ave, Greenside, Johannesburg, 2125. This year I call to lodge a complaint about the batteries that are no longer holding in charge, they ask me to bring them in so they can test, I drive from mpumalanga bethal to them, get there iam told to leave the batteries so Siyabonga their technician can run tests, then he gives me [06/15, 10:19] Kosabo: 3285 INU Ref 0/N65880 as reference, a month later he calls me to say they will exchange the batteries..week later I send a courier company to collect the batteries, when I get home to connect the batteries they still do the same thing, they can't hold charge for even 30min, and when I call and text my calls are hang, my texts are ignored, now I don't know what to do with this situation, iam always in the dark with this loadshedding and iam having zoom meeting daily, now iam suffering because of poor after sales service..please assist, I can also screen short the conversation on whatsapp as prove.
