Vodacom Menlyn Walk In Customer Centre - Unprofessional, poor service delivery

iPhone Volume button needed repairs. As it was under warranty, I took it to Vodacom WICC. Before it was sent to Vodacom, we were instructed by the Technician, Ziggy that the phone content had to be backed up. I was forced to buy a 64GB flash drive from the store for R229. The Back-up was an extra R280. The shop assistant Audrey completed the Job Card (***). She took the entire phone with the phone cover (Worth R249). I was notified 10/02/2023 that the phone had been replaced and was ready for collection. I phoned twice on 10/02/2023 and pleaded with the Store Repairs Back-office that they have the flash drive available so that the phone could be set up in store, as I had paid for the service already. When I arrived on 11/02/20023, Ziggy had no idea where the flash drive was. He also took over 2 hours to attempt to set the phone up. He claimed the phone did not have enough storage to set up. However, the phone had exactly the same storage as the previous device. He still had not uploaded the flash drive content to the device. I demanded the phone and the flash drive back and left the store. I RUSHED to Vodacom Brooklyn, where FLOYD was my saving grace! Within 45 min, Floyd managed to restore the 5G backed up to the iCloud, and set the entire phone up. The flash drive WAS EMPTY. There were NO FILES. Not one single backed-up image, contact, document - NOTHING. I had to buy a new phone cover and pay for the data retrieval and set up of the device - all because Vodacom Menlyn Walk In Customer Centre were unprofessional and unable to deliver the service I paid for.
