Bad attitude from consultant

my sister and i had a terrible experience yesterday at western union at mall of Africa.We go to the branch around 5.45 and we realised we needed an ID to send money .I then told the consultant i was going to fetch my ID while my sister remained completing the slip to send.The consultant advised that i should be back by 6pm other the door will close and i will not be able to come in.I then rushed to the car to fetch my car and was there by 5.59pm. then one of the consultants started shouting at us telling us we they were closed and would not be able to assist.i told her it was 6pm on my phone and i was already in and she started screaming at us telling us her watch says 6.03pm and she will not be able to assist and if we had a problem we should write in their complaints book.She continued having a screaming contest with us and told us to go to OR Tambo.I believe her name was Zoleka or something like that. We then went to the lady who assisted us initially and she also refused to assist saying her colleague says we came in after 6pm. i am appalled at this service and they realy represent western unioun in a negative way.there is no customer centricity at all .Even retail shops dont dont do that .I am trully disappointed and hopefully you will train your staff to have ubuntu.
