Quite disappointed

As a huge huawei fan, i am very and extremely disappointed at the device i have just received. In just 8 days, out of box, the device switched off and refused to come on completely. Furthermore the cell phone provider has refused to replace it due to the fact that it has exceeded its 7 day out of box period which i feel is totally unacceptable and unreasonable. It appears to me that huawei gives only 7 day guarantee for their phones nowadays and this is lousy. Why must a brand new phone be taken for repairs and sent back to me and i must be satisfied? If it is giving me such problems in just a week, how much more will it trouble me in a month or two and in the near future? How many times will i have to book it in at my own espense. Is it that huawei know that their products are becoming useless now that they have hit the market big and are therefore only giving 7 days and any trouble after that is at our own expense? Is this how loyal customers are treated? Im very disappointed.
