Lies to get customers to purchase vouchers

Contacted the company to check for a booking on a specific date, they said there was plenty bookings available. I mentioned that I saw a special for the company on Groupon and was told that I could either buy the voucher or get the same price in store and pay cash. I had Groupon credit so I used it for the voucher. <br> <br> She said contact her when I bought the voucher and send the voucher to her to make the booking. When I did she said there is no bookings available for the next month. After talking to her for a long time she finally revealed that there was bookings available, but for customers with Groupon vouchers they schedule them and the next available session was in 1 month's time. If i wanted a booking for that specific day I need to pay cash (even though I already purchased the voucher).<br> <br> She said that's the rule they follow and she said she was the manager, and that the owner made this rule. But she would not let me speak to the owner.<br> <br> Very bad business practise, lying to a customer to purchase a voucher then giving them a hard time to make a booking. She also claimed my voucher before confirming an appointment which lead to hassles getting a refund from Groupon. Stay away!
