Not replace till date

Jai Hind, Sir. I am Nitish Kumar Singh. On October 20, 2024, I purchased a 55-inch Haier TV from Dada Dev Electronics in Polm, Delhi (Mobile No. [protected]). On the morning of September 6, 2026, the TV display stopped working, so I colled Haier customer care to lodge a complaint (Complaint No. HI[protected]). A technician visited on September 7 and diagnosed a faulty panel; he charged a service fee of 21,180 and left, stating that personnel from the Noida service center would arrive to replace the unit-since it was under warranty-within 24 hours. However, I received no call or visit from Haier; whenever I call, they keep giving evosive answers like "today or tomorrow." It has been four days, and they have caused me immense trouble. Sir, a common man saves up money to buy such expensive items, yet companies cheat customers like this-what will become of this country? Strict action must be taken against them. Please, Sir. Thank you.
