Tata Sky — Issues with the connection

I have been using tata sky connection since 2017... Somewhere in 2018 i relocated and relocation installation of tata sky was done by tata sky people only... Now here is some issues with the connection and that needs a technician visit to check the alignment of the dish or  wearing... For which i need to pay for technician visit and cost of the hardware...

As installation was waranted for a year...

So i do not understand when installation was done by tatasky then why should i pay for technician visit... As i have already paid for installation...

So sir this is not the way of doing business you still need to learn how to do business... I will think that i have paid money to begger tata's... Who does not have courage to take responsibilities of their own product...
