I-On — Disconnected internet after paying money

Address:

Rayadupakalu road, Kolamuru, Rajahmundry, Andhra Pradesh 533102

I have paid 6 months money and now internet provider offers cable connection free of cost. I requested them for new cable connection which is free and included in internet fee. Now I am asking for cable connection from last 4 months Evey time they re saying they will keep. But now they have disconnected my internet with out any notice and talking rash.
