Makro does not adhere to T&C's of their own

I am now posting my third complaint. Makro clearly is not the business to deal with. I made a purchase of a laptop which was not working, I returned it which took 10 days for them to agree to take the return. Now after waiting two weeks for them to tell me I will get my money, they said 5 to 7 working days. 5 Days later they sent an email saying they need proof of payment, copy of my id and banking details. When I bought the laptop they did not need any of this information. After sending them the email, with the documents, they reply asking for the documents. Clearly makro is attempting to relieve me of my money and hope I will give up and they can keep my money. the call center staff are so rude, and if they cannot answer they just merely hang up. No managers work on a Sunday and to speak to a team leader, you need to provide 20 pages of information and waste your airtime to be put on hold and not get any help. I now do not know what more to do other then to go into a store and create a scene
