Sisa Thai Spa business owner shouting at a client for writing a negative review

I bought a voucher from Hyperli for a massage at Sisa Thai Spa (voucher # LJWMPDG5). 1. Firstly I called the numbers that was listed as the number to call to make an appointment. I called several times without any answer and it was during their working hours , so meaning no one is manning the phone ----red flag 1 2. Eventually they come back to me they give me 9am slot. I arrive at 8h53 to allow myself time to start my treatment at 9am, the ladies that work there were not there.----red flag 2 3. I tell the lady that she was late as my appointment is for 9am and she still needed to open, prepare the room and heat the oil. She was not happy with my statement ---red flag 3 4. I wrote a review on Google, the owner calls me shouting at me for writing a review about my experience. She told me their normal open at 9h30 but the opened at 9 am to accommodate my appointment (I did not ask for that). She gave me 9am and I expected them to honor the appointment. She tells me there was nothing they could have done to please me because I complained about the time. Yes I had the right to complain because they were late---red flag 4 5. She says we buy the cheap vouchers on Hyperli and come and complain about the service. I told her I did not post her business on Hyperli, she did. She knows she posted her business there because it is struggling and it is not my fault. If I pay for a service, I expect service.

@Hyperli please speak to your merchants, we can't be verbally abused for writing negatively for their ****py service.
