Worst experience ever for returns

After being unhappy with the laptop I brought at makro woodmead I returned it for a refund. I waited a few day to check if I didn't damage the product, they finally called me to get my refund. They don't even inform me of the type of docs they gonna need to refund me with the type of payment I made. I get there and they ask for letter of account since it's not a credit card, I gave them also a copy of my ID unfortunately I had forgotten my makro store card so my friend borrowed me hers to swipe and I paid the consultant told it does not matter it will be put back into my account. A few days later, they can't give me my money back because it doesn't match the makro store card, but from which bank account does it come from? Mine but you still refuse to refund me, I toldy friend to send her details and still not refund. I'm honestly disappointed and angry at the service you giving me, it's unfair and uncalled for.
