Disgusting Customer Service from Lotus Thai (Faerie Glen)

I have been going to Lotus Thai Spa in Faerie Glen for years. But today was definitely the last time that I will be dealing with them. I phoned them to find out if they had an opening for myself and a friend for a 60 minute massage to which they rudely responded "we're FULL". Mind you, I phoned twice... Once two find out about the massage and second to make them aware of how they were treating customers. So, just to make sure, I again asked: "are you sure you're full, even if it's 8pm?" Again, they said "we're FULL". They were not polite, they did not say "unfortunately" - SWEET ****** ALL! So, on my third attempt, I did the next sensible thing... Phone the cellphone number on the website and I asked the lady if she was the manager, to which she did not answer but said that she could not help me. I was not interested, as I wanted to speak to someone higher up. I insisted on this, as I did not want to speak to her, then she started shouting at me, I confronted her about how she was speaking to me and then she hung up. I tried to phone back a few times and she never answered me. I am disgusted and I really hope the appropriate owner / person in charge deals with this and I would really appreciate it if someone could get back to me because this is NOT how you treat customers.
