Worst ever experience buying a cellphone. ****y staff and even ****ier manager

On Monday the 22nd of September, I bought an iphone 16 at Vodacom Canal Walk for R17500 cash. I used it for a few days then all of a sudden the camera button stopped working, after that it gave me problems when taking pictures. I returned it on Saturday (27/09/25) well within the 7 days of return. I was told they will have to book it in for repairs, I tell the agent helping me this isn't right because now I won't have a phone and he becomes ****y towards me telling me it's up to me. Fine I allow them to book it in, then I receive an email telling me my phone is ready for collection on Wednesday (01/10/25) I call them to confirm this, they tell my claim has been rejected because my iCloud wasn't removed from the phone, I tell them that isn't my fault that is the person who was booking in the phone that was supposed to ensure that. I end up going in store to resolve this, they give me no solutions, telling me they have to rebook the phone, because of this, my thing is that was not my fault, I did everything on my end, it was negligence on their end. Fine I end up leaving with nothing, today (02/10/25) I call them up, I first got a hold of their sales manager who kept on telling me they cannot issue me a new phone. Now my thing is it's either I should be offered a new phone or refunded my money, I have neither of those as speak. I also got a hold of the manager who was very ****y towards me telling me there's nothing she can do. They haven't been helpful at all and their service is poor, I am still waiting for I don't know how long to get my issue resolved and they aren't being any helpful at all. This is the worst ever experience I've had buying a cellphone, their whole staff is ****y offering no solutions but no problems. I need my cellphone or my money back. This is the worst ever store.
