False advertising on specials and bad booking service

I recently received an sms from Placecol Willowbridge reading " Book any 1 hour facial and receive a free treatment" When I sent an e-mail to enquire regarding the free treatment, they mentioned it is either a back and neck massage / express pedi or paraffin foot treatment. I rep**** to the e-mail by Jackie and made a booking in advance for 15:00 on the Wednesday. When I got to the salon there was no booking and the beauticians managed to shift some clients and I could come back at 15:30 that day.They asked which facial I would like to book and mentioned the 1 hour Hydro Cocoa and Nvuo was going to help me. I hanged around in the mall and received a call to at 15:20 from Yolandi saying the special only applies to the R575 1 hour facial not any of the others. I went back to the salon and showed them the sms. So Yolandi mentioned something that it was a different special and not her special and they will be able to help me some other day. There was a student there doing her time and she was very willing to help, offer to do the massage for me while someone else does the facial. At this point I was quite irate as I was told I will be helped at 15:30 and I waited around for 30 mins and now again it was an issue to help me. The relaxing experience of a facial just became a very stressful and annoying experience. So Yolandi said in future I need to come in with the sms and show them before I make a booking. I told her that I was not explained that it was only the R575 facial when I sent the e-mail and she suggest not to book via e-mail in future. How is that for great service!
