Runway Sale customer experience nightmare

I'm am so disappointed with the service I have received from Runway Sale - not only do they have the most deplorable customer sales service but the delivery times provided are a total fabrication and are highly unrealistic. I placed my order two weeks ago in preparation for my birthday dinner as the items purchased were for my party outfit. My order status had not changed in over a week and one of the consultants I spoke to by the name of Carla, provided empty promises and flimsy excuses (warehouse power failure, logistics company delay) and was not helpful at all. Managers/Supervisors are never available to speak to customers and I'm still waiting for Carla's manager, Ilse to return my call since last week. I have yet again had to call today and to my horror I have now been informed that my delivery has been further delayed by another week!! I am so disappointed that my parcel will not arrive in time for my birthday, this is so unacceptable and unprofessional!! It is the second time I have been let down by Runway Sale and I honestly wish I stuck to purchasing my outfits from Superbalist or Zando who are more efficient and have far superior customer service. This entire experience has been such a nightmare because now my worry is they may deliver my parcel whilst I'm on leave, which they are aware of. Runway Sale may have great discounts however their post-sales service and turnaround times are an absolute nightmare!!
