Honda Cars India Ltd. — axon honda ghaziabad looting/thuggin the customers

Address:

Ghaziabad, Uttar Pradesh, 201001

I had sent my honda city diesel on servicing to axon honda and after the servicing car runs around 1000km and i found that engine oils decreased about 700-800ml. I had visited them again and they checkednthe vehicle and said its normal. Vehicle is perfectly fine.
Now today i have again sent the vehicle for service and ask them to fill the engine oil in front of me and i also asked the measurement container.
When he fills the container with the oil comes through the automatic pipeline the meter reading shows that the oil is 4.2 ltrs accurate as per honda norms but in the container the quantity is 3.7 approx which means they filled the engine by 500 ml less as per the standard keeping the vehicle on risk also charging more than the supply.
I didnt expect this from authorised honda dealer that they are looting us like this and we need to doubt them everytime.
Also, the store manager abusing the mechanic that why you have fill the oil in measuring container and shown to the customer.
Beware honda you had a brand name please check as few dealers are spoiling it.
Adding pics for your reference.
