Bad service Ackermans Blueroot mall

Phone sent for repairs 9 december 2020 phone for my son, no feedback from them untill i went to the store 7th feb 2021. Employee told me she will call me monday. Monday she called saying supplier has passed a credit note so i must come for refund.

9th i get to the store, i was told that i cant get cash back i must get refund on a gift card. I told the lady i already have a new phone now for my son as they took to long to resolve the repairs issue.

So if the supplier passed credit to ackermans blueroot mall. why am i getting a gift card refund. The only thing the emplyee told me was that i must phone customer service. Why phone customer service where the store could have even called thier superiors about this issue to find a way to resolve it.
