Bad Service Sterns Ballito Junction

I bought 2 rings last week Sunday and the service I received from the 2 ladies last week Sunday was excellent. I bought 2 sizes as I wasn't sure of my husband's size, whe I got home the bigger size fitted him. I tried to return the small one today 10/11/2024, however when I got to the shop the lady that assisted me said I couldn't change it as I needed to bring the other ring that fits my husband which was strange, I asked her but the other ring doesn't have a barcode to why do I need to bring it she said because it was buy one get one free which didn't make sense to me.

I called my husband and he suggested that I leave the ring with her in the shop & he would go tomorrow to exchange but the lady asked me to send her the invoice as it was sent to me electronically. I emailed it to the email address she gave me, she kept on checking her screen and she didn't receive the invoice. I felt she was not helpful, not willing to assist in any way, I got frustrated because I thought the email is showing sent on my side and she saw the invoice from my phone, but insisted I had to email it, but this invoice was sent to me from their system why couldn't she get it from sent items from her system so I decided to leave the shop because I didn't get help and the lady was not willing to assist in any way. So I've got this item that my husband will not use and no one can use.

Thank God what I bought wasn't expensive so going forward I'll never buy from Sterns Ballito Junction ever again, this was a very bad experience.
