Unwillingness to assist

Went to the branch to collect my online purchase and was met by a very unhelpful Elna (seems to be a floor manager). This is not the first time that I collect an online purchase at this store without an order number. However today this was a problem and she advised that she could not go look for my parcel by name and surname as there might be more than one person by that name (I highly doubt it). I advised her that the account holder is my husband and that the order number was sent to him, however I do have both our Id's with me. I was just told to contact him. She waisted my time and petrol. Elna, you can learn something from your staff members, as they were more helpful than you. Maybe you need to take a course on customer service, you were not helpful at all and left my angered!!!!
