Unhappy!!

I placed a order for a pc board on the 22.01.2025. I paid R937. 25 for the pc board. My client informed me it was the wrong one, i then contacted Livance and they advised me that i can return it i just need to pay in the difference for the correct part. I sent back the wronf pc board, but never received the correct item or even my money back. I have made numerous attemps to get my money back but to no avail. They are *****sters!!!
