Cash converters

I am deeply disappointed with the service I received at Cash converters in Springs mall. On the 16th of February 2025 i purchased a kettle and to my little knowledge of electrical appliances i was not aware that the kettle only works on a stove. I went back immediately after buying it but was not assisted. I asked my colleague to return the kettle for me since i was off duty, again they gave her runaround demanding a receipt that was never even given to me since their system was off and was told to pay via the speed point. I went back the following day since i was on duty and when i relayed the story to the store manager she confidently told me that there is nothing that she can do since the item had no warranty and therefore cannot be returned. I asked her what the solution is since I do not need anything else in the store? She told me again that there is nothing she can do. I feel ****** of my money and time I spent there without getting any help but being told that I should go sell the kettle so i can get my money back. I have never heard of such a response from a person that is entrusted to run the store. Is this how cash converters us of our money?
