Soul Serenity Day Spa - very disappointing

I would just like to say how utterly disgusted I am with Soul Serenity Day Spa. It is Monday morning and I am still waiting for Audrey (Spa owner) to contact me with atleast an apology. Mother and daughter owned Spa in Randburg really does not know what proper customer services is. I have been a faithful customer that has spent ALOT of money at this spa on facials and products. I called to the Spa on Friday morning and spoke to Jasmin and asked her if I could please move my appointment from 11h00 on Saturday the 14th of November to 14h00 same day and also order products. Jasmin said my appointment was confirmed for 14h00 and that my products would be there. However I get a call at 11h15 from Jasmin asking me why I have not arrived for my appointment. I was abit confused and my response was but I spoke to you yesterday and you agreed to move my appointment to 14h00. Jasmin did not accept the or see that she had done something wrong and continued to argue that I could be not accommodated at 14h00 as they already had a booking. I can not understand why they would double book. Out of characters, but such poor service.
