Disappointing Service

I have been calling BestMed for 3 days straight now. The phone just rings, Ive been on hold today for 15 minutes before hanging up. They have not answered the phone in the past 2 days either. I have also sent numerous emails to ask the consultants to call me back. No one has called be back. I wanted to join this scheme but the fact that I cannot even get through or get someone to call me is making me very doubtful. They might be loosing a potential new client at this rate. How do they do business? How do you expect new clients to join if you are not available to explain your product to them? Makes no sense
