Appalling service

I went to Ackermans in Birch Acres centre in Tembisa to cancel my lay-bye and I was told I would be given a voucher because I didn't have the original proof of payment. I went on to my +plus more account and I found infact an e-receipt. I was first told I need to go to an internet cafe and get a print out and even that wouldn't work because it's a copy, said the cashier as she walked away. The lady who seemed to be the manager (authoriser) just stood there in agreement and watched the whole thing. I was then issued an e-voucher with no one asking me whether I would like the voucher electronically or any other way. I find this to be very poor in service and a double standard honestly.
