Poor ********* service

I Purchased a Nokia C10 on the 22nd October 2021 at Ackermans Dobsonville store, on the 3rd November the camera stopped working and I took it back to the store on the 05th November 2021 for repairs. I was called in a week later to collect the device only to find that the device is still not repaired and it was taken back to vodacom for the second time. After a week again I was called to come collect the smartphone and it was still not fixed and no one was willing to help me I waited at the store for an hour without being assisted, I was told to go and they would contact me with a way forward. I asked if they can credit my money back into my account and to date in sitting without a device and no communication. I called the store last week and they said they would call me but no has called. I'm very frustrated with the service that I receive at Dobsonville ackermans store.
