Cavendish Square Poor Service

Hi there, I called your Cavendish Square store and first could not get through. I eventually got through to the store and Christine booked my appointment for 16H00 which was apparently the only time they had available. I then booked my hair appointment for 3PM to accommodate this. She then called me back after 1PM and asked me to come in at 2PM because they had double booked me, and there was now way that I was able to get there by 2PM. I also spoke to Erin, who did not even apologise and then I cancelled my other 3 bookings for next Saturday. This is unacceptable as I frequent this salon. I also wanted to use my birthday voucher and this was the only day which I had free to do this, and now it will go to waste.
