Apple India — iphone 7 complaints

Address: New Delhi, Delhi, 110024

Dear Team,

I have purchased Apple iPhone7 from the Lajpat Nagar iNvent store on[protected] at cost of Rs.58500.
There are many issues that I am facing with this phone which are mentioned below:

Voice is very low the person from the other side is not able to hear it.
Network issue means people call me and they say that your phone was not reachable and also I get message from my Airtel Missed call Alert that someone was trying to call you.
Not able is use internet, internet is very slow however when I use in other phone it works fine.
Also sometimes it freezes for 15 sec and automatically starts when you press the power button.

These are the problems which I am facing however I went to Apple Service center (Pacific Mall Subhash Nagar) first time they said that there is a problem with your software we will update it and it will work fine, they restored and updated the software after updating everything they tested and said there is some other problem also so leave your phone for the observation, so I said please give me another phone to use and they said we don’t have right now, so I said that I will give you by next week and please arrange a hand set for me they agreed on it.
And when I went again to service center they checked and said there is no problem in the phone when I insisted that there is a problem which was earlier recognized by your team member, but they denied and said if you are saying it then submit your phone for a week we will observe and if we find any issue then we will send it Bangalore, I said ok please give me phone to use so that I can submit my phone for a week and they denied on this they said that if Bangalore team will approve then only we can give you the phone and the team leader was talking like we are not responsible for this and we cannot give and he was talking very harsh as If I have made mistake by purchasing an iPhone the Team Leader was very rude.
If by paying Rs.58500 I am not getting the services then I think it’s worst. Please suggest a way around otherwise I have to take support from the consumer forum.
