Samsung Mall of Africa - No refund ?

The Samsung store in mall of Africa is very disappointing. I sent my galaxy watch in for a battery replacement. After many months of poor communication from the repair department I finally got my device back. I only started to get response to my request after I posted the poor quality of service on hellopeter. To be clear when I booked my device in, it could power on and function correctly but the battery drained very quickly, only lasted about 1h. When I finally got my device back. It switched on but it displayed a white screen and it kept vibrating and was in essence useless. I asked for a refund and the technician requested that I email my banking details to him and he will start the refund process. I email my details on the 30/11/2020 11:29 AM. I received an email in response that same day 30/11/2020 11:52AM with “thank you sir”. I followed up on the 16/12/2020 by emailing the same email requesting some information on my refund. No reply was given. I email then again on the 14/01/2021 requesting some information on my refund. Awaiting my reply….. Iam very disappointed with the level of service of this shop. This store front is dragging Samsung SA name through mud.
