Airtel — network issue never resolved

Waiting or almost six months, constantly following up with airtel customer service get my network issue resolved, all in vain
No body has bothered to visit my place to assess the issue. All i receive is one generic response that they are working on the upgradation.
Six months past and nothing worked, customer services refuses to give a timeline for resolution.
Sent an email to nodal, and they asked me to wait for another week, post one week will complete appleate and launch a consumer redressal

Have vented out my frustration in constant tweets and fb posts
Don’t know what to do.
Airtel customercare is one of the worst in my experience
