Poor Customer Service

On Saterday the 16th of May 2020 i went to Ackermans in Scottsville mall in PMB..i got to the door @ 12:25 and the door was locked with 1 customer waiting outside the door..i was followed by 2 more customers and then the door was opened by their staff member letting a customer out and he signalled to us to say the shop is still full with customers inside..we waited patiently until at 12:40 a lady came to the door and told us that the shop is closed...and we all asked how come because the opening and closing time signage says shop if opened from 9-13...and we were told to wait as there were customers inside..meanwhile the shop was empty...because we were complaining. A senior staff member was called and she said they close at 12...i questioned the signage outside and she opened and let us..in such a rude and irritated manner she was shouting and saying they close at 12 as they are now sanitising the shop ...we requested for them to change the times put outside for us...as i was still looking around at the clothes...she shouted from the tills and said make it fast...we want to close...i was not happy with the way she treated customers as the other customer left the shop...customer service is important...no customer should be treated the way they treated customers...the lady that told us they close at 12:30 is Prudence if i am not mistaken.
