Apple India — Manufacturing fault in i Phone 7

I have purchased I phone 7 with the IMEI NO. [protected] one the very first day it was launched in India with a very positive mood but my excitement was turned into a nightmare when I discovered that the phone is not working as it should work on the very next day of purchasing, it shuts down by itself sometimes its screen goes black most of the times it gets hanged and doesn't works at all, I approached the authorized service center MAPLE in R-City mall Ghatkopar west with the MOST ARROGANT STAFF and told them about the problem but I was shocked to hear when they said that the phone is working good as per their system and I should do factory reset which I did right in front of them but it did not work as it should be working and I was told to try it at home, second time I was told to leave the phone fpr three days so that they check by them self but nothing improved this complaint was repeated more two times with no proper response from the service station where the people only know to say this is companies procedure we cant do anything, then I asked them why are they wasting peoples time by playing false and tricky games with them, now after complaining fourth time they discovered that the phone is not working properly and it needs to be sent to their head office to find out the real cause of the problem and after one weak time they came up saying that there is a problem in display and that they are going to replace it. my point is when the phone had a manufacturing fault why should I take a repaired phone at the cost of new, they should have straight away replaced with a new one, now if the they don't change it I ll have to knock the doors of consumers court, I am really ashamed of buying this product and moreover the quality of the service we receive from their authorized service outlets its so embracing to sit in their service stations like culprits and the way they behave after you have paid the high price for it specially the arrogant people they hire to attend the complaints on the front desk. I hope this should help a bit . I am really sorry that I have purchased this product and assure it won't be repeated in future. And if this site is really not helping people out of their problems then even this site also should be closed instead wasting peoples time siting and writing complaints.
