Rude behavior from staff

The behavior we got here is ill and unacceptable .The staff members have a ill behaviour. I went to the shop to buy some few things and I went to the shoe department I then asked the staff for help she completely ignored us and carried on walking we followed the staff member and asked her for help she then told us that she didn't work in the department and we should find someone else to help us.We then went to another staff member and asked her she didn't reply to us and carried on with what she was doing.She took her own time before she came to assist us this was unacceptable
