I am gutted by the service from Montblanc Hyde Park

I am so disappointed and in disgust by how the hyde park corner Montblanc store provided me with horrible service . I reserved a product on the 20th of Jan and received a call from one of the stuff members on the 21st informing on the that the product will be at the store on the 25th and she will call me when it arrives. Monday the 25th came and I didn’t get a call as promised I called the store and ask if the product has arrived the salesman assures me that it is in store, I then said I will be coming in the following day(26 Jan) to view the product before it goes to be personalised. On the 26 of Jan I travelled all the way from Pretoria to Hyde park to be told that the product has not arrived and they are out of stock, I wasted my precious time and money. The way the stuff that was present treated me was uncalled for it was as if they were in a hurry to close the store. The salesman that was present took my details and promise to check with the sandton store first thing in the morning(27 of Jan) and will call me asap after to inform me on the way forward. What was also a shock I was told that to have the product embossed I would have to pay extra while on the website it is free. The salesman never called. Disappointed is an understatement for the service I experienced from such a "luxury brand".
