Poor Service level

Vodacom Shop Secunda sold me a iphone11 that has factory defaults 26 Sept, I returned it 3 Oct. Now i am without a phone due to the leak of client satisfaction. meaning i wont be able to do banking or communicate with friends and family. because they expect everyone to have a second phone. meanwhile the factory default is not either both our problems. They can just give me a new phone and take the damaged phone to the manufacture.
