Tata Teleservices — My Landline No[protected] is not working for past 18 months

Address:

Shop no- 10, Shanta Bldg, 18 June Road, Panjim Goa. 403001. Landmark- Behind Vivanta by TAJ

My landline No[protected] is not working for the past 18 months, tried contacting the TATA Office in Goa but was told everytime that the customer should buy 50 mtr Phone wire, draw the line from pole to the building and only after that their technician will come to rectify the issue, this is not acceptable by any consumer.
I also tried contacting the service provider on Toll free and email but was of no help at all.
And after 18 months i received a call from TATA asking me to pay Rs.200/- phone bill as my line was active, i only requested them to fix my phone and i will pay the bill.
I have lost business as this was my Office landline, many customers would call me for my products.
Kindly Help
