awful service - 5 months later & I don't have my watch

On 31st Dec 2019 I bought a Huawei GT2 sportswatch from Sportmans Warehouse. From the start the heart rate was way too high. On 23rd Feb I took the watch to the Huawei store in Somerset Mall. I told them I would be out of the country for 4 weeks. I got back 2 days before lockdown so had no choice but to wait. I called the store mid May & was told the watch was in Joburg. After a few calls the store manager admitted that he wasn't getting any response about my watch from Joburg & that I should contact the area managers. The business service manager didn't take the call nor call back as per request but the WC service manager took my call & got back to me to say he tracked down my watch. That was before 18 May. 29 May Mario says he will be sending my watch to be exchanged (where to if it's already in Joburg since Feb?) & will have a replacement by 3/4 June. Long story, back & forth with lockdown, sterilisation, courier issues excuses etc I still have not got a watch! Mario isn't taking my calls anymore. I don't know where to turn to get my watch or my money back. Such awful service!
