Bad Service Hi-Online Riverside Mall Nelspruit

Bought a Tempo digital watch November 2022, the watch stopped working 15 January 2023. On the invoice it said the device has 6months warranty, took it back to the shop and was first told they don't book inn watches. The watch was then booked in 17 January 2023, had to enquire now and then with regard to the progress in store. I didn't even get an sms to tell me the progress. Only now in 17 March 2023 I was told they will refund me or I should take something in store worth the amount I bought the watch for. Mind you I bought the watch whilst it was on sale, now I won't be getting another watch. When I went for the refund it's stories again saying they haven't processed my things.
