Very bad customer service from store and regional manager

I got a new phone Samsung Galaxy A31 on the 11 February 2021 from telkom The Grove Mall. On the 15 May 2021 the screen went dead but the phone was still on. The was ringing but I could not see anything on the screen and could not answer it. So I went to Telkom The Grove and explain what happened and the phone was booked in for repairs. I was told it will day 21 days but I will receive a call to inform me about the progress. I waited and nothing happened. So after several attempts to try and contact the store on this number *** with no success I went to the store on the 10 June 2021 to find out what is going on with my phone to my surprise the phone was still at the repair place and not fixed yet hence the agent that booked the phone in did it wrong. I lost my cool and ask that I want to talk to the store manager but the store manager was not in that day so I ask to the sale person to call the regional manager. She did and the regional manager by the name of Jeanet told me she will phone and find out what the problem is. I waited in the store from 12:30 until 15:30 just to learn that they can't replace my phone due to the fact that it was discontinued so I will have to wait 5 more days than I will have my phone back. I told the regional manager that this is unacceptable for my and she told me that she is not even working on that day but she will se what she can do. Today is day number 7 and still no call or any communication from anyone to inform me what is happening to my phone. I would like someone to please help me with this matter because I can't phone Telkom customer service to complain. If this is how telkom service they customers than I regret that I move to telkom.
