Worst Service in the world

I bought my son an I-phone 6+ on the 16July 2018 at Edgars eastgate, on the 1st of November 2018 the phone was returned because the screen was frozen

We were called on the19th November 2018 to provide passwords for i cloud ,we were told a new will be given to and on the 23rd November 2018 I went to give them the password,so that they can excess the phone and the phone was switched on and they said they will send it in for repairs

On the 3rd of December my son witnessed that he was online on whats app, but the phone was in for repairs .So on the 10 december 2018 we went to the store and they confirmed the phone was back from repairs two weeks ago, but no one notified us

So they tried switching it on and the phone wouldn't switching on so we were told to hang around while they charged it and 2 hours later store assistants said their charger must be faulty we must take it back home and charge it

We got home and the phone wouldn't charge or switch on, the following day we went back to the store and requested to see the manager but he refused to come, since he spoke to the staff through telephone but the staff said he was in his office in the store

He told the store assistant that a new phone must be chosen for the same amount although it wasn't the same phone

We asked to have the same I-phone 6 plus we can pick it up from another branch and it was the most frustrating conversation, as it was a dialog between myself and the store assistant who constantly had to ask the manager via telephone call instead of a manager coming to us as we requested to see him

According to staff members they must send an email to other branches to find out if they have this phone and in my experience I was so astonished by what I was told, send an email?how about phoning them?or how about the system where you scan the barcode and it shows all the stores that has it

I was then told by the assistant since the manager wouldn't come ,that transferring stock from one branch to the other (IBT) can only be done through the head office and the conclusion was that I will be called once they sourced a new phone I-phone 6 plus

I have been waiting for feedback since then , no one has phoned me yet and I am still hanging onto a dead phone I can't do nothing with it,the phone doesn't switch on.The service at Edgars is horribly shocking I constantly had to drive there the whole time because no one cares about a customers there
