Disappointed

I purchased a cell phone on 25.04.2025, I experienced what I thought was bad signal. About the second week the phone randomly switched on & off ,While on a call the sound just faded & finally stayed off.i took it back to the store & it was sent it for repairs. After about 3/4 weeks it returned & I I was told that it's back on,I asked about the other issues & no notes was sent back from many. I got home & still at didn't charge this on a original fast charges & calls still fading. I went back to the store asked how its possible to send a new phone for repairs. I did not even fulle use this phone for even 2months. I was advised that pecan send it back to repairs. I refused that as this is supposed to be a perfectly new phone in perfect working condition. I was advised to speak to management. I sent an email and was advised that head office will provide feedback and waiting to date. While I use a phone for business I could not bare loosing any further business and decided to purchase a better phone. On the 09.08.2025 I then bough a pre owned I phone after the transaction was paid for and then only the consultant opens the box and tells me that it has no accessories especially no charger or an cord. I was puzzled and called my daughter that has more experience and has a better way of communicating. She called the consultant and went to the store to speak to him and the manager. It was said that the phones are brought in as is. Why not make the client aware of this before charging the account t and signing the paper work. I felt this to be very strange as any other store even with reopened cell phones has the cable incl. This would mean I would have the burden of spending more then I already had to buy a cord and adapter for almost r2k. Some calls and questions and then "big boss" decides the will not return the phone. No explanation no accou stability. Yet I'm expected to pay for something I can not use and it's dead. Shot down twice.
