Huawei melrose arch and national bad service

Please dont buy a huawei phone you will save yourself lots of heart ache and problems along the line, i tried to replace my battery on my huawei mate 20 pro with huawei melrose arch as they are supposed to be running a special on battery replacements and guess what they dont have stock and they dont want to order the battery unless you book in your phone meaning you will be without a phone for at least a week and have to drive up and down, also dont try to replace the battery yourself as it is paired with the pc board and wont boot up. Also dont try to call their service centre as they do t even know what is going on and gives mis information. Me personally am done with huawei and will never support them again.
