Bad Attitude

I received a Spa voucher as a gift for 2 people on the 28th of April. However at that time I noticed the expiry date was the 30th of April. So I called the name of the Beauty Studio that was on the voucher. I called many times that phone just rang. I again tried to call at about 4.30pm. And a lady answered just hello. I honestly did know if was indeed the correct no in manner the Lady answered the phone. I told her that I have a Spa voucher as a gift but it expires on the 30th of April. Can I book ann appointment for Saturday at about 11.30. The name of that Spa is Sharaella Beauty Studio in Rosebank. However she was very rude and spoke over me all the time saying she's fully booked for the weekend. Yet ai called her before the expiry date to book the appointment. So I asked her for an appointment for next week. She very rudely said I told Im fully booked. So I asked to speak to the manager and by this time I was so frustrated by her bad attitude towards me. She told me that she is the manager. So I told her that she is coming across to me very strongly and aldo continues speaking on top of me. Thdn she told me that I must foward her the voucher with the redemption code on watsapp which I did. At the same time she told me that she will get back to me about the appointment. She never responded to me even though she blue ticked my msgs. Then I called her when I asked if she got my message she said yes. I was ste speaking to her to please book for the 15th May while I still talking she cut the call. I was calling her again and again. She never answered. Then I get a watsapp stating that she will not be able y book me because she will not subject her staff to my rudeness. How can I now be rude when she was and when I told her that she was coming across to me very strongly. I don't apw her rudeness or rude comments about me. I never even spoke to anyone there but just her. I am at her shocked behavior. Her name id Zeena. So she said.
