[Resolved]  Tata Sky — fraud by tata sky technician and overdue unresolved service issue

After facing repeated signal issue for around 6 months, no permanent solution was provided. Then a tata sky visited and asked to put a new part on our tata sky dish and took cash of rs. 875 for the part. 15 days later when we again faced the old issue, we come to know from another tata sky technician who visited my building that 1) the part was not correct and tata sky had no records of the said part replaced 2) the dish on which it was fit tree was not ours! 3) insoite if informing tata sky about the fraud done by their technician they have not reverted back.
After a week of writing email to tata sky nodal office, still. Nobody has visited to solve the issue.
