unhappy client with bad service

We just been to Makro Bloemfontein to return Ballpens 100pk - we bought a lot of stuff at Makro for our offices on the 07/03/2018 with an amount of R4500.00 - The pens were damaged and we would like to return it, We had our slip with the pens and now they said its a procedure to show your bank card if you paid by card. We told them its a debt card and not a credit card we just want our refund of R169.00 - Last time we were there they wanted A ID - this is unacceptable - the money is already in their bank - we just wanted the refund to buy other pens. The bank card we used is our company's business card and this card is not with us every day - we just get the card when we need to buy stuff for the business. We tried to explain it to the lady in the refund department. The ladies in the refund department was not very helpful and when we requested to see the manager this guy also did not want to listen to our complaint. This is not the first time that I experience that clients been treated like this in Makro
