Half info received

I went to Weight Watchers in Glen Marais, to make a change in my life. I filled in the forms and paid my money. I was not told by the consultant Vone Botha that if you do not come and weigh in every 2 weeks then you have to pay R90 penalty fee. She is only available on a Saturday morning for 1 hour. When I told her I will not be able to come at the times she is available, only then did she informed me about the rule. I lost R500 because of the most important rule that i was not inform with. They are very quick to take your money.
