Anyone used the Huawei repair centre yet ?

[Ks45672]

I managed to somehow crack the back glass battery cover while walking with it in a front jeans pocket (Huawei mate 10 pro) 

 

The spare back part is very cheap on Ali express and ebay ($10-15) but  tricky to repair at home because its glued together very tight for waterproof and I don't want to risk breaking the expensive side ($250) trying to remove the back ..... 

 

Anyone know what Huawei are going to charge for a job like this? (part+labour) 

 

I know third party fixers can heat it up and swap the part but rather use Huawei  unless the price is way over the top

 

(can't bring it in for an official quote yet because I haven't time till Saturday or Sunday )
