Bad Service Edenvale shop

I bought an AC-Dc adapter to charge my lamp during lockdown on 5 July 2022 The shop is in Edenvale called Evertin U at 47 Van Riebeeck ave Edenvale I called on them today as mt cable stopped working The owner was so unfriendly and not interested to help me in any way Surely a cable lasts longer than 4 months but then again it is made in China Doug Miller ***
