Airtel — net is 2g

I am using airtel for last 10 years. I have taken a plan for 4 g but net connectivity in my mobile is 2g for last 15 days.
I am unable to use my internet connection for office work as it is 2g and very slow while i am paying for 4g.
I have talked to airtel customer care several times but no outcome. Kindly lodge my complaints and get me reversed my rentals for this month as it is providing 2g connectivity after lots of complaints in airtel customer care.
