HTC India — wifi no connection crnica fault

Address:

8000-327

I have an htc one m8 purchased in portugal and after 3 years the wifi no connection fault persists after sending to agent twice first time zero cost now i have been quoted 380 euros +23% taxes.
Since this fault is not caused by the phone operator i sincerely expect from htc nothing but to have the phone replaced.
Appreciate to be contacted to my mail [protected]@yahoo.com
Kind regards
