Appalling ,unacceptable behavior from Letty at Mall@reds branch

On Friday morning the 18th of May I did my shopping at Pnp Mall@reds,I had a price query at the till for an item ,since the packer could not assist, I requested further assistance.This Manager (Letty) was so arrogant and unhelpful from the beginning as if i was bothering her.I tried to explain the situation but she already had her mind set on the outcome. After wasting my time from us going up and down the aisle to get the right price ,she just said thats how it is now go.Talking and mumbling in her language. I wonder is that how she speaks to all customers.I decided to leave all my shopping and called the Store Manager.Leaving my shopping did not seem to bother anyone. How does Pnp employ such a rude and *********** person that does not even know the basics of customer service etiquette.I would appreciate some feedback about this incident.
