One Cart advance voucher

Good day I purchased One cart advance voucher code(OCVA-hyimNv) amounting to R150.00, I've received my voucher code but not the QR Code, and my account were debited. After numerous attempts and being send from pillar to post, and a lot of frustrations Evidence(service ticket number ***) at the call centre, which by the way provided me with excellent service, escalated the matter to the technical department. I've received an message on Sunday 2. October that service ticket number: ***'s closed, needless to say I still have not received a call/and or my QR Code.

I want to re-itterate that Evidence provided me with excellent service, was very helpfull and was willing, to assist me to resolve this matter, wheras the other consultants were not very helpfull, only willing to "pass the buck" Please assist
