ACT Fibernet — Cheating with Bills and zero connectivity

I requested for net connection for new location, they charged me 826 Rs bill and I paid. But no one supporting me for connectivity. And in invoice it's clearly showing bill is 826 Rs, but they told me they is no extra charges only 10 days bill. Now they are saying 400 Rs for shifting and and rest is net bill and again they said now there is extra 246 payment I need to pay. It's really shocking to me with amount they are Generating bills and talking in different approach. I need my amount back
