*********. Not offering services I already paid for.

I spent R1 400 on a hair package. I had 3x blowdry's left. I wanted to make an appointment today and I was told they are fully booked and unfortunately I won't get an extension to use the rest of my package. So unfair because it's not my fault you are fully booked today. You guys want the money upfront but are very ********* when it comes to offering the services already paid for.
