Yellow canal walk offers poor service. I am so disappoint after purchasing the Samsung Z flip that retails for R30 000 from them.

I was last night at telkom canal walk to take my faulty Samsung Z Flip back after just using the phone for 7 days and the phone started heating up on day 3 already and a snowflake screen appears during voice notes. When I took the phone back they denied me a courtesy phone, they denied me a new Samsung z flip and said that they going to send my phone in for repairs which will take minimum of three weeks. My husband had to call the manager Ryan at the canal walk branch and negotiate with him for a courtesy phone as my phone is my primary business and income. The manager Ryan then gave me a P8 Huawei which is super slow and I cannot access Facebook where I market my business and clients are unable to get through to me because of this. I am highly disappointed as I bought the most expensive phone on the market and in there branch and they couldn't assist me with a reasonable courtesy phone.
