Bee MP3.com/Billingaid.com / overcharged/billing

I found this BeeMP3 site and wanted to try and download a song. Paid for the $4.87 3-day trial, not the $39.73 membership. Tried to download the song and it didn't work so I thought maybe the payment didn't go through, so I tried to sign up and pay again. Now I have been charged twice for $39.73 and a few other small charges(foriegn ATM and/or point of fail fee??). I only wanted the trial for $4.87! Contacted my band to get a number and got this number for Billingaid.com: [protected]. Called them and was hung up on twice because I asked about the overcharges. What Can I do to resolve this?
