Disgusted with Apple iStore service

On the 10th of October 2018 around 9am I booked in my phone at Lochlogan iStore in Bloemfontein. The camera on my iPhone 7 was cracked, so it needed to be assessed by Apple. On the 11th of October I received the quotation estimating the damage on the device. That same afternoon I requested a letter explaing the exact damage on the phone as well as a clear explanation stipulating if the phone could be repaired or if the phone should be replaced. I had to forward this letter to my insurance company. The email I received back was a job sheet saying nothing more than the original quote. I emailed again and explained the situation, the email I then received stated that they already provided me with the insurance letter. I then went back to iStore to ask for assistance on a letter which my insurance company is asking for, after a huge struggle I was provided with a job sheet, which still was not stating that the damaxge on the is so extend that the phone is beyond economic repair.
