ACDC electrical shocking service when requesting a refund

I recently purchased a bunch of emergency LED lightbulbs to help light our home during load shedding. I requested warm white bulbs which were said to be delivered the following week. After returning to the store 3 times and being told that the stock still hadnt arrived, even after I phoned to check that the order had arrived, I eventually decided just to purchase the cool white bulbs.

Once home I discovered that one of the globes didnt work and that the light was too harsh. I returned the globes within their 5 day return policy. When asking for a refund the staff dragged their feet in helping me and then I was told to write down all my details and submit a photograph of the front and back of my debit card, along with a copy of my ID and a copy of my bank statements. In a country full of ***** and *******ion I feel this is ridiculous becasue any member of staff who comes across my details can clean out my account. I stated I wanted my details removed from their system as soon as the refund was processed. It took over a month for them to do the refund even with persistant emails from myself remidning them about my refund. Once completed I asked if my details had been deleted from their accounts database, to which I received a response stating that ACDC hold loads of peoples and business account details and that they wont de***** me and so wont remove my details. I will never shop at this or any ACDC electrical store again and will not recommend them to my worst enemy.
