Samsung Watch Ultra 2025

On the 19th September i purchased a Samsung watch 8 ultra Vodacom Mall of Africa Samsung Samsung Electronics. I fully charged the watch the Saturday evening and the following Sunday morning i needed to use it for a race and it was completely run down. I fully charged the watch at 9 am again the Sunday morning and when i arrived at the store mid afternoon it had depleted the battery by more than 50%. I returned the watch within less than 2 days of purchase. I was told that the store needs to follow protocol and the watch was then sent to their repair centre. A few days later the watch was returned after diagnostics was run and no techically fault could be found. In store I showed the staff how quickly the battery is running down. A Samsung representative was present in store and indicated to the staff that the battery of the watch is not functioning optimally. A video was taken and provided to the technical staff of vodacom indicating how quickly the battery runs down. Again the watch was sent to the repair centre and returned within a few days indicating that the watch is functioning. It's been 3 weeks since I've purchased the watch which I have not be able to use. As a loyal customer of Samsung Global Vodacom I'm disgusted in the service that I have received. As a consumer that has returned the product within 7 days i should have been able to get an exchange on something that is clearly not working optimally. I'm frustrated since no-one seems to can provide proper answers and i constantly need to follow up.
