Huawei Operating System is Pathetic

I am very unhappy with the Huawei Operating System, it is extremely user-unfriendly. When I purchased the phone & contract at the Telkom store at the Pavillion Mall in Westville, I did ask for an android phone/operating system, but the sales lady did not even mention that it came with a Huawei Operating system. She did not even ask me about my needs with regard to a phone. I went back to the Telkom branch at the Pavillion Mall (near Pick n Pay) several times and there was no Huawei technician to assist me, each time he was out to lunch. The Huawei App gallery does not have many of the apps that I need to use. After-sales service is disgusting, to say the least.
