Mg Motor India - Heavy Service Cost

MG sucks!!
I have just finished **k service last day. (Invoice No.S***S********, Dated **-Jan-****, Coastal Garages, Kochi) I wanted them to replace the wiper blade, beyond the routine service. Do you know they are charging ****+ rupees for the normal service? There were no parts replacements!
They enforce the customers to replace the AC filter at every ***** km! They argue that it is a mandatory replacement not to void warranty.
They advertise that MG Hector runs at ** paise per kilometer to bluff their incoming customers. If an IC Engine car's running cost is **ps/km, how much would be for an EV? There's no oil, clutch fluids, Air filter, Fuel filter, Canisters, or Engine-Radiator fluids etc., to replace in EVs. Still it's **+ paise per km!!!
