Bad service for simply returning damaged product within 24hrs of purchasing..

I went to vodacom Southgate mall on the 28/09/20 And I bought a i phone charger.. When I got home I charged my phone and and when the battery was full I removed the charger and the pin (silver flat inserter) got stuck on my phone.. On the 29/09/20 I went back to return the charger and show them what had happened but the lady and the guy there on my face said that I broke the charger.. 1. How do I brake something the same day within 2 hours of buying it? 2. I went to vodacom straight because I had hope and trusted that I'll get the best quality seeing the price. 3. The returns policy clearly states that I HAVE 14 DAYS TO RETURN THE PRODUCT IF AM NOT HAPPY WITH IT OR NOT COMPLETELY SATISFIED. 4.The consumer protection act of South Africa states that 1 has 6 months to return a product that is damaged.. 5. I had the receipt with wich confuses me as to why wasn't I refunded or given another charger.. 6. The worst part is that i was treated soo bad that the lady and the gentleman called security for me.. For simply asking for my money back on the product that is visibly damaged.. I have been a vodacom client for a long time now and I didn't expect this from them.. I feel it is not fare and certainly not good for business if clients are to be treated like that when they spent their money..

Can vodacom kindly refund me my money soo that I can take my business where I will be valued as a client and get value for my money.. Your response will be highly appreciated..
