Boat — Can't select City

Website:

support.boat-lifestyle.com,

Hi, I have submitted a warranty claim request before from pincode 497001 for my boat Bassheads. I was going to order new boat usb cable for my phone and thought of checking the boat support site for warrenty claim before buying and now If i enter my current pincode 497001 I can't select the city as its locked but I can fill other details normally and when I proceed it says to select city and its not only with cables but all other products too, when I was claiming my warranty for Bassheads i haven't faced this problem. I would buy realme's usb cable as i can get their warranty claimed easily. Please look into this issue.
