Telkom has failed me.

I sent my Iphone for repairs at the Telkom Kennilworth centre on the 2nd of May 2018. My charging port had had stopped working and i submitted the phone for this issue to be remedied and i received a message two weeks later saying that my phone had been fixed and so i had to go and collect it. I did collect the phone, entered the security code which the phone rejected. I was then advised by a consultant at the Telkom shop to take the phone to an I store, where it was reset. I tried to log into my i cloud account but failed then went back to Telkom to make them aware of this. They sent me back to the I store and didn't have adequate travelling fare to make my way there so i went home and put the phone away. Then two weeks later i received a call from Telkom informing me that they made a mistake a gave me the wrong phone. They then sent a gentleman named Tory who claimed to be a store manager to collect the phone. I accompanied him back to the store demanding that i be given a phone to use in the meantime.He gave me a phone to use in exchange for the one they had given to me wronly. I found out later that day that the phone had software issues and i could not use it. I went back to them to report to them that they had given me a dysfunctional phone and also check on the progress of mine. Mine had not been fixed because the warranty apparently had expired. Although what puzzles me is that when i took the phone to them, the warranty was still far from its expiry date. Today i received a call from a Nizaam, who requested to be given the username and password so that he could switch off the find my Iphone. He said that the find my Iphone has to be switched off in order for the phone to be fixed. Your assistance to this effect would be highly appreciated. Thank you and good day.
