Cash Crusaders the Gluttons and exploiters

I bought a Samsung S24+ for +-R14000 from your Mimosa Mall branch in Bloemfontein. About a month later, I tried to resell the same device after I made upgrades such as putting on a privacy screen. When I took it back to sell the device, they offered me R3000 for the exact device; no scratches nothing. It was as they sold it me. Cash Crusaders take advantage of people's desperation and their attitude is take it or leave it. This is manipulation and greed of the highest degree. I've pawned gold items at the Heidedal store and they refuse to give me the amount advertised. It's always less. I used to be a regular customer but but making over 400% is ridiculous actually it's glutinous.
