@LGIndia .@LGIndia then sent me SMS asking for a SATISFACTION CODE.

Satisfaction. For a repair that never happened. By engineers who never came.

8 days. CEO Office. MD Office. 5 escalations. ₹2,600 out of pocket.

This is your AMC. 🤡

📢 Update: It's been 24 hours.

@LGIndia has registered my escalation (No. VCP260420066159) but zero callback, zero rescheduling so far.

My AC is still unserviced. I'm a paid AMC customer.

Clock is ticking. ⏰ #LGIndia #ConsumerRights #AMC

[Sumantra Joshi @sumantrajoshi]

@LGIndia @LGIndia "escalated" again. 5th time in 8 days.

Yesterday I gave up & paid a local guy ₹2,600 from my pocket. He found a COIL LEAK your engineers never bothered to check.

I have a valid ₹6,490 AMC. My 81-yr-old mother is in 40°C heat.

[Sumantra Joshi @sumantrajoshi]

@LGIndia @LGIndia has "escalated internally" 5+ times in 7 days.

AC still broken. 81-yr-old mother in 42°C Delhi heat.

₹6,490 AMC = worthless. 🤡

[Sumantra Joshi @sumantrajoshi]

@LGIndia This is what ₹6,490 AMC from @LGIndia buys you:

✖️ Unauthorized cancellation
✖️ Broken promises
✖️ Contradictory pricing
✖️ 6 days, no technician

@LGIndia 🔴 Day 6 — @LGIndia
MD Office called ✅ CEO Office complaint filed ✅ Emails sent ✅
Resolution? ❌
Now getting contradictory quotes — ₹1,750 yesterday, ₹2,000+ today. Not even sure if what my AMC covers anymore.

My 81-yr-old mother is still in scorching Delhi heat. Shame. 🌡️

[Sumantra Joshi @sumantrajoshi]

@LGIndia Service Call: RNP260417063098
Escalation No: VCP260420066159

Both registered. Multiple assurances given. Zero action taken.

@LGIndia — how many more calls and emails before someone actually shows up?

#LGIndia #ConsumerRights #AMC #Delhi #Heatwave

[Sumantra Joshi @sumantrajoshi]

@LGIndia 🔴 Day 5 — @LGIndia

MD Office called. Email received. Assurances given. No one showed up. Again.

My 81-yr-old mother is in scorching Delhi heat. This is what a paid ₹6,490 AMC gets you. 🤦

@LGIndia I tried reaching out via the LG Support Assistant chat — waited in queue from 9:51 AM to 10:00 AM. 7 "Your chat is in queue" messages. Not a single agent responded.

Customer care lines? Not picking up either.

This is a service contract. @LGIndia

[Sumantra Joshi @sumantrajoshi]

@LGIndia This is unacceptable.

I raised a service request (Call No: RNP260417063098) for my AC (SRH) last Friday. Status went from "Pending for gas charging" → now changed to "Cancellation requested" — WITHOUT my consent!

Nobody asked or informed me. The job just CANCELLED. 😡

[Sumantra Joshi @sumantrajoshi]

@LGIndia To make it worse — I paid ₹6,490 for an AMC (Annual Maintenance Contract) valid till Sep 2027 (Form No: 17199395).

I am a paid AMC customer and THIS is the service I get? A ghost cancellation? No technician. No call. No resolution. 🤡

The AI bottleneck isn't compute. It’s the autoregressive trap.

Mercury 2 (a Diffusion LLM) shatters this, hitting 1,000+ tokens/sec.

🔹 Standard LLMs = Typewriters
🔹 DLLMs = Editors revising full drafts

What will you build with this speed? https://t.co/ixiSYh634k

Cheat Sheet from the video:

You can stack 1,000 layers & burn $1M in compute.

But if you forget the Activation Function, your "Deep Learning" model is mathematically just: y = mx + c 📉

The "SaaS-pocalypse" isn't coming. It's already here. 📉

On Jan 30th, Anthropic released a simple "folder of text files" that quietly decimated the legal tech market.

You can’t understand deep learning until you understand one neuron.

I made a whiteboard video explaining the perceptron from first principles — no jargon.

In Bihar’s voter list revision, more women than men were deleted under “death”, 11.6 lakh vs 10.6 lakh.

But official state records show men account for nearly 60% of all deaths.

Hello @TSeries, stop being a stooge.

Parody & Satire comes under fair use Legally.

I haven’t used the lyrics or the original instrumental of the song.

If you take this video down every cover song/dance video can be taken down.
Creators please take a note of it.

Having said that every monopoly in India is nothing short of Mafia so please watch/download this special before it’s taken down.
FYI - T- Series I stay in Tamil Nadu
