Unprofessional and bad service

I went to Bride&Co Canal Walk on the 20/01/2018 to have a look at the dresses. When I entered the store and was approached by the lady at the front desk saying you need to have an appointment if you want to view the dresses. I said I was not aware of that and asked if I can view. She said there are only 2 consultants available and they have client but can have a look. I selected some dresses to fit on and was waiting to fit it on. I asked the lady at the reception if i can fit it on. She asked one of the consultants and I had to hear the whole story about appointments but she will keep an eye while she’s busy with the other client. The time I was fitting on I have not seen nor have she come and ask if I need assistance. When I made my selection and on my way to the till, she came to me.I told her there’s buttons missing on the dress and she said they most probably used it for another dress. I asked what the price was as the promotion was 75% off .The amount on the tag was R2400.00 and the price it scanned on the till was R2500.00 and she said the discount is R500.00 and i paid R2000.00. I told the lady that the price differ from the tag and she said but that’s the price. I was told they going to get other buttons and will let me know the next day or by latest the Tuesday. To date I have not receive a call nor does any communication from neither the consultant nor the store with regard to my dress.
