Double charge and still no refund nor communication in return

I am truly disgusted with the treatment of your staff at your Sole Victoria Road branch. December the 11th, after making numerous calls to your branch to book 3 treatments for a colleague and being placed on hold 3 times for over 15 minutes a time, I walk into the shop to make the appointments. I wait and wait while the front desk chats casually on her telephone. Finally after waiting for about 10 minutes, I am greeted with a grunt. I then complain about the telephone service and receive a shrug of shoulders. I then try and book the 3 appointments and get told that there is no way they can assist as the bookings are full. I ask the lady an alternative - which she should provide me with and not the other way around. After booking, I make the payment on my card and I insist that the lady please staples the receipt into the appointment booklet because the 3 treatments were purchased as a corporate gift for a colleague. I leave the contact number of a manager at my company, so that Sole can contact them if they required and I was off on annual leave to Australia. The appointment day comes and the treatments are done - but them the staff threaten the client and do not let her leave until she can supply proof of payment? I was in Australia and there is no way that this lady could have contacted me. With an appointment ending at 4/5pm, it would be 1/2am in the morning. So, your staff try and make her pay?! I insisted that your receptionist stapled the POP into the book and then you guys try and make her pay again. This lady did not have the money to pay and had to contact another colleague at work, after working hours to assist her with this matter. So then, this other lady has to come into town and make an additional payment. You have now double charged us and we have yet to hear back from Sole! Are you trying to rob us? I have emailed the mail address on your webpage as well as Victoria Road and Lucy - but there is a failure to respond. This is ridiculous and we demand a refund of the double charge and an apology for this awful treatment.
