Poor inconsiderate customer service!!

I am not happy with the service I received from Game Jabulani mall on Sunday and again today (Monday).

All I wanted to do was exchange of blind that I purchased on the 23rd of March 2022, explained to the lady that I lost my slip however I have proof of purchase as I paid using my card and that it is still under the 21days returns/exchange policy however she was not willing to assist me!!! Secondly the shop assistants at the appliances section kept me waiting for over 30 minutes as they were busy chit-chatting, when I clearly stated to one of them that I want to lay-bye a tv and only 30 minutes later did they advise that their damn systems are offline!!! something that could have been done before keeping me waiting.

This is totally unacceptable and I expect feedback on the above as I want to return this blind that I do not need!! Nonhlanhla - ***
