Huawei repairs *******

I have a P20 pro that had a manufacturer's defect after updating the software. The fingerprint sensor settings all disappeared and the phone started heating up and battery draining. I booked the phone in for this matter after discussing with a consultant, and was then sent a quote for a screen repair even when my device did not have a cracked screen. Apparently they do not do "partial repairs" even when the issue is a software factory fault, you are still required to pay for every other problem or potential problem they find. I found this very unfair as I would never have booked my phone in if I didn't do a software update. After speaking to several consultants, I gathered that the repairs are done by contracted company which their policy to Huawei is do all repairs and not partial. My warranty and service commitment is with Huawei and not the 3rd party, so I challenge you Huawei SA, what intervention or service do you actually offer the customer without blindsiding them and draining money from them? This issue was brought upon you and your software defect, now I am left with a bill, without a phone and still waiting for your correspondence and intervention going on to 3weeks.
