Pathetically bad, misleading service

My fiance visited Bride&Co at the Durban to view dresses in April this year, she had tried a few dresses and was pleased with one dress in particular however due to the fact that this was the firs store that we had visited she decided to continue shopping. After months of searching for a dresses we had noticed the dress that she had initially fell in love with was on sale and it was an ideal time to purchase, before going to the store again with the intention of making a purchase we decided to go on the Bride&CO site to have one more look, she came across another dress which she also liked and wanted to try on to make a final decision however the consultant advised us that she did not have the dress online but would get it in a week while the sale was still running. The week had passed and the consultant did not call, i took it on my onus to call the store only to find out that the sale was over but they did obtain the dress we requested to view but when the consultant called us there was no answer, when we confirmed the number the consulatant took down there was a digit wrong. We contacted the store manager which advised that we would not get the initial dress at the sale price
