Mr Price Langeberg Mall - BAD SERVICE!

Mr. Price Langeberg Mall Mossel Bay. I was busy buying a gift voucher and after i swiped my bank card was asked to supply my ID nr to which i kindly declined. The teller said that it’s policy when buying a voucher which i thought was a bit weird. Anyway, i still refused to give my ID and requested a refund. To my knowledge i’m entitled to ask for a refund, right?! The supervisor (i think) was asked to assist in the matter and she started getting snippy with me after learning what the issue was. I told her exactly what i told the teller and that i would like a refund. After I waited about 3min the supervisor asked me with a tone in her voice if i’m waiting for something else. So i said i’m waiting for you to tell me where my money is and that the transaction is reversed/finalized. She searched the system and surprisingly found the transaction. She tried but could not do the refund and called the manager. She told the manager that i refused to give them my personal information. The manager approached me and greated me. She then told me exactly the same thing as the supervisor did, probably thinking that the bigger rank will have more impact. I said that no where does it say that i have to supply any personal information when making a voucher purchase and that I would like a refund please. The manager then also rep**** with a tone in her voice that they will put the policy up on display. After having to restarting the computer they still couldn’t do the refund and ended up using their own details to finalize the transaction. How unprofessional. Shame.
