Flash sale

Was a big huawei supporter but now ashamed to even be using a huawei phone, they advertised a 90% off black Friday deal... I had to go take out a loan for it, suddenly it changes to limited quantities, but then only 1 person can buy, why even go through trouble of advertising to millions of people if they cant get it if they want it? I looked forward to the flash sale all week and wasted so much of my time researching the phone and falling in love with it, when the flash sale finally goes live the website crashed and it was not updating the flash sale deals on time as indicated on the live stream, when i could finally view the deals it was already out of stock, not only did i waste my money, time and data, this also affected me emotionally because this is something i was really looking forward to, only to be failed by the website saying system busy when you try to click anything.
