Honda Activa — activa 4 t oil price more than mrp price

Dear sir,

I am subramanian living in tuticorin, to purchase oil from your dealer in tuticorin south tamil nadu, last month i purchase oil rs. 235/ including tax. To day go to your dealer the same acitva 4 t 800 ml oil price is rs.252/ in billing but mrp price is rs..235. Now i am cancelled my bill and buy other outlet
I am really shocked are you cheating me or your dealer cheating me. I need clarification from your end.02.05.2018. My mobile no : [protected]
