unprofessionalism

Hi I bough a voucher from GMH Marketing for Salon Sanri for R200 where I could get treatments and some discount as they are a new salon doing marketing. I called them this morning to make an appointment for a cut and blow. I said that I could not come in week, then she said she could help me on Saturday but it not as per voucher, but the voucher states trading hours Sat 08am to 4pm and weekdays from 8am to 18:00 and she could only help me in fourweeks time, and if I want to come in week i must be there at 4pm but can only spend 1/2 on me. Sorry noboy is going to shampoo, cut an blow wave my hair in 1/2 hour, it be just a rush. If I am not happy I must call Garth and he will refund me. No No, they should refund me as they cannot help me. This voucher is only valid for 4 months, so everytime I call it will be an issue to help me, so then I would never be helped at all. This is so unprofessional. I did call Garth and he said that he would change my voucher for another salon. Most definately this Salon Sanri does not want any new business. Why do marketing if they are so busy, why do they then need new clients. If my business was important to them they would have mad a plan.
