Lenovo — Petty issue made big

I had a simple power cord problem. I told them I'm willing to play since they acted like money lynching parasites, said we can only help you if you had "Premium service". Then they said even if you pay we can't help. So the only way out is to get a premium service plan for a 150Rs/- cable? I was willing to pay 750 for that cable but they were not willing to arrange or help. Or even offer an alternate solution, their so-called "Team lead" Saya Azim never responded!
