Poor Service Poor Customer feedback Poor Experience overall

I have been waiting for so long to have my Samsung watch repaired, a watch which am still paying for but am not able to use because of the *********** person who is supposed to repair my watch, I initially took my watch in for repair at Samsung Mall of Africa store because the glass on the back of the watch protecting the sensors was coming off (the glue was wearing/coming off), the watch was “repaired” but hardly a week past and the watch just stopped working (it heated up and went dead) upon close look/inspection at the “repair” done I notice the glue was also put on the sensors of the watch I took back the watch to the same guy to repair and he said it was somehow my fault and that I sweat too much, I complained to Samsung and he then said it was the battery that was the issue, he ordered a new battery and replaced it, I went back again to ask how far was the repair and he said he ordered some other small parts and would be done soon, Then lockdown begun (so I understood that nothing would be done due to the restrictions in the country), now we in Level 3 and the shop was opened in level 4, but till today my watch is still at the store I went last week to ask again about the repair and this time the guy says it’s the sensors that is the issue, when I said that to him to begin with and he just denied that the glue on the sensors was not the issue, now suddenly the sensors need to be replaced, I do not trust that guy to do a good job on the repair he doesn’t know what his doing and would like Samsung to step in and take the watch to be repaired elsewhere or get someone else to repair it. I still do not have the watch and I bought that watch to use it for my runs, not for some guy to practice his repair s****s on it, please assist me in this matter. Hardly any communication to let me know what is going on, and I must keep driving to the store to get updates, which is money and time I do not have.
