Poor service for device return

Upon trying to return the device for a refund at Randpark Ridge Mall, MTN store, I was abruptly informed by the store agent that I cannot get a refund for the device. When I queried this, the manager told me, without a mask on, that the device is not faulty, the phone is entry level and just because I am not satisfied with the product that this is not a reason for a return. The store manager proceeded to tell me that I was told about this when I purchased the device, which I was not, and I asked the store manager how he would know what I was told when he wasn’t part of the sale. There should be a cooling off period, where as a consumer I have the right to return the product. I tried to reach Customer Care on 083 135 to query the return policy for the device purchased on 2 November 2021 from Randpark Ridge Mall, MTN. However, there is no option to speak to an agent.
