Authorized Service Provider charges more than site estimate
I want to change the battery in my iPhone 11 Pro Max. The Apple website gives an estimate of around $89 for this service, even when selecting my local (Costa Rica) service providers. However, when I called them, they quoted me for $169.
Are these centers allowed to charge what they want or do they have to abide by the estimates in the Apple website? I find this price extremely high, almost as much as the phone’s worth now.
