Waterdrop Vending Machine

My husband & I were invited to listen to their machine presentation last year. We have since paid in full RM33K. Income not good , less than RM500/m. Waterdrop claimed can earn RM2,500 per month. Request them to re-locate ,but still drag on and on. Has been 1/2 year since delivery. I have requested relocate machine, but seems no action. Claims that its capital guarantee. I'm in doubt now. I want full refund of my investment, RM33k. How to go about doing it? Please help... We are not rich people. All our hard earned money. Pls call me to advise me how to take action.
