Nightmare experience

I made a terrible mistake of ordering my dress at Eurobride Menlyn Maine with Natika in January 2019 and was informed the dress will be delivered in June .On the 25 of June I called to follow up on the delivery date as I did not receive any update, unfortunately the receptionist couldn't provide me with actual details regarding the order and delivery date as she did not assist with sale of the dress and the sales person (Natika) was off on Tuesdays, I found this very unprofessional that in the absence of the sales person I couldn't be assisted. Natika eventually called me on the 26th of June and assured me everything was in order and that the dress would be delivered on Saturday the 29th of June and worse case scenario it would be delivered on Monday the 1st of July, on the 1st of July she did not give me any feedback and on the 2nd of July I called again to enquire about the dress, and again the receptionist didn't have any further details regarding the dress and Natika was not at work,I requested to speak to Natika's boss only to be told she is not in the office and I should send an email which I did and was not responded to(I had already sent an unresponded email on the 26 of June ) ,I also requested that the owner/regional manager call me back which she didnt, I also requested Natika to call me urgently today when she gets to the office which she hasn't. This is the worst service ever and for the prices they charge I wouldn't recommend their shop to anyone ,they give the worst customer service.
