Shocking service from IStore Menlyn

Purchased an expensive RING doorbell in November 2018. It stopped working in November 2019. I returned it one week out of warranty. The manager, Grant, said he would contact RING and call me the same day re how to get it repaired. Heard nothing. Two days later I called the Istore (general) number - they called Grant who said he would get back to me the same day. Heard nothing.A week later I returned to the IStore. Grant had left and the new manager, Chris, was to get back to me the same day. Heard nothing. 2 weeks later, after the Xmas break, I called the IStore (general) number and spoke to Thembela. She called Menlyn and assured me they would get back to me the same day. Heard nothing. Thembela called the same day to ask if I had heard from them. I said no and she said they would surely call the next day and I heard nothing. A week later (yesterday) I called the IStore (general) number. Thembela was busy but said Chris would contact me yesterday. Heard nothing.
