Samsung customer service centre is a disgrace

The Samsung customer service centre in Pretoria, the Grove is a real dump. On 21 February 2020, I took my phone and charger in to report that I am no longer able to charge my phone. After testing the device and charger, the technician told me it's the charger that's faulty, they'll place an order for a replacement since my phone was still under warranty. A month later, not hearing from them, I called to inquire about the progress. Nonchalantly I'm told the charger has not arrived, we'll call you. In our first encounter I was told this has a turnaround time of 10 working days. Anyways couple of weeks later, in April they called to say I can come and fetch the charger. I get there, the technician wants to see my actual phone. I give it to him and he starts pressing without communicating what he's doing on my phone. Moments later I ask him what the heck. He says he is installing some software, he can't release the charger without updating my phone. I was there forever and the software would not install. So i said boet, I need to go i can't wait for this forever. The guy wouldn't give me the charger and told me to come back. This was at the start of the Corona Pandemic and he was okay with me driving back and forth so he can install some ******* I didn't ask for on my phone. Anyway I'm still without their replacement charger and had to buy myself a power bank. Wow what a loser!
