I'm never buying from vodacom ever again

Yesterday I bought an iPhone 11 at Goldfield mall in Welkom. What happened is that the lady whom I bought a phone from did not check the phone if it's working or not she gave me the phone. On my way out from the shop I remembered to ask about how to charge the phone and so forth because that was never discussed with me. I went home when I got home the phone wasn't switching on, I assumed maybe it's the charger and I charged the phone wasn't charging. I went back to vodacom only to be told that the phone Will be taken for repairs on Monday mind 3 hours hasn't passed since I bought the phone. I spoke to the manager and she handled the situation very well and they borrowed me a phone and said I she doesn't have the phone on store so she will order a new 1 it should be here by next week Wednesday. I'm so disappointed in vodacom because I've been buying from them and I never encountered this kinda problems before. I'm thinking they're going to fix that phone when it comes back they will give it to me. I'm not going to take an opened phone while I bought a new one and the 7 days has not passed yet and I didn't even use that phone to begin with. I'm so angry write now and disappointed in vodacom.
