Petronas review: disappointed of behaviour staffs

I went to Petronas Kulis Am Induk Service at PTD55821 Jln Kebudayaan 19 Tmn U, Skudai JB around 12pm for deposit the money at atm machine inside.
Suddenly, ladies staff with no manner/rude ask me to wait coz need to talk with me. Am I supposed to wait when she need to talk with me?
So disappointed when the ladies staff talk rude with me about parking car issues. Im really not satisfied when being treat like a hell while im a pregnant and with a heavy rain.
She says im not bring any business to her while im only going inside just to banking the money. Is it the right ways to say? With the loud voices and rude words to me. Im so angry and she so arrogant while ask me to make a complaint if I dare. Im so dissappinted while im actually a regular customer with Petronas over 10years. She also admit she is a manager for the company who incharge all the business. I ask for the boss contact no for explaination but she ignore me. I directly go out from the station n drive my car out.
