I want to know if you will replace wifi and Bluetooth Antenna for my IPhone 7 Plus! This is my question! Give me a direct answer!

i want to know where can I replace my IPhone 7 Plus Wifi Antenna? The apple service Center in Bangalore India ( Kormangla) does not have the skilled people to do it. Do you have anyone who can replace the Wifi and Bluetooth Antenna? I don’t want a direct answer! I don’t want anything else! Everything works well on my phone! I don’t want you to keep diagnosing it unnecessarily! I know the problem. Just fix it! Last time they diagnosed the phone for issues unnecessarily, charged me for that! Didn’t come up with a solution! I know the problem! Everything functions well except for Wifi Antenna and Bluetooth! Just give me a Direct answer if there is a service to replace the Wifi and Bluetooth Antenna on iPhone 7 Plus, I am tired of searching for this from the past 3 years!
