Customer service non existing!

The service of iStore Cavendish and most likely apple/ iStore as a whole is virtually non existing any more. I wanted to bring in a iphone XR that has a faulty camera (gyroscope). This is a known fault to apple since iPhone 8 and it is advertised on the website, apple will fix this free of charge IF......... I was supposed to leave the phone there because maybe more breaks???? Like what?? Worse even, they could not give me a time frame. maybe 5-7 days, maybe 3 weeks maybe 2 month. So instead of having stock of the camera (which is a KNOWN FAULTY item)like any other company, I am asked to leave my phone for a undefined period of time in a shop, on my own risk (last time my laptop was damaged in a iStore i was told they TRY to fix it) and I have no guarantee if and when I get my phone back. Deirdre O’Brien& Joz Joswiak, Apple, with (non existing) service like this, you surely will loose your last loyal customers!!
