Bad Service

I brought a TV at Hifi Corp on the 23/10/2019 that is still under warranty as it was not giving a picture. I was told that the waiting period is up to 21 days. On day 25 I called them to find out what could be a delay as I have not heard from them yet. I was advised that someone will return my call immediately and they even took my number, after 24 hours as I was still not contacted as promised I took initiative to call out of my precious time and was asked to hold while they find out who supposed to call me back, to my surprise a call was put down on my ear as I was holding and no one even bothered to call me back. I then concluded on my side that they hung up intentionally. I'm disappointed and dissatisfied with a service I received from the Jabulani mall branch.
