We have 3 lines from RIL

We have 3 lines from RIL, two are point to point, and one is broad band- Internet. All are E1 line. In every 15 days our P2p line are having major issues of wire cables, may of CSU/DSU units, which only have supplied. We have contacted so many time, opened the tickets, only they are keen to close the tickets. There is no permanent solution on it. No is taking care of this. GOD knows who will help us in this.
