Garmin terrible service

I bought my Garmin Venu3 from Sportsmans Warehouse in Vanderbijlpark in November 2025. In August 2026 my watch started to glitch, I would switch it off and on and it would work again. Then it started to happen more often, at the end almost every hour, so I took it in with my proof of payment to Sportsmans on the 7th of October 2026. The watch was only collected on the 16th October after I had a massive fight with Sportsmans, who blamed Garmin. I am a fitness instructor and part of Vitality, the fact that I have been without a watch for this long has lead to me missing out on my Vitality points and makes my life very difficult being without a watch. I was sent an *** from Garmin saying they have the watch and it will take 7-10 day to asses, so I asked when I will be able to get my watch back. Garmin have not responded to me regarding my watch and I dont know how long im going to wait to get it back. This has been such bad service from Garmin, im extremely disappointed with the whole situation.
