Not excellent customer service and returns suck.

I purchased a Samsung phone end of July and when I opened and switched the phone on it already showed me a screen with green lines bouncing up and down. I contacted Makro via WhatsApp, useless agents ofcourse so I took it into store. I waited a full month for this phone to be repaired,I only received 1 sms with the repair number. Anyway my phone got delivered back to me a day after I called to ask what's happening,mind you I've called Makro Ottery over 7 times at this point to hear what's happening. My phone got delivered again mid August, we are in the first week of Sept 2024 and this phone is acting up again by bouncing and also restarting every 30 minutes, I've sent emails ad called and contacted Makro WhatsApp but to no avail or alternatives,the WhatsApp agent only says to take it back to the store which I won't cos I have a job that's nightshift and have no free time to use my waking minutes to stand in a returns queue. This is ridiculous customer service when I made it so clear that somethings wrong with the phone since I bought it and since the repair.
