Realme Tv — Horizontal stripes in tv display

Hi,

I purchased realme tv.
One day it suddenly started to show horizontal stripes on display.

I had raised the issue and the technitian visited. He said some panle needs replacement and went.

It has been more than a month now since he didn't come back.

I call the service center, they keep saying once the part is available, the technitian will visit again.

I belong to combined family and we have eleders at home who are too habitual of watching TV.

There was also a complain raised ref #CC[protected].
I was told that some one from senior management will call for better resolution but nobody called.

I am tired now taking follow up from them.
I don't know what to do next..
