Insight Visa Insight Credit Card Doesn't work Internet

I Purchased and activated an Insight Visa prepaid debit card to pay for my gym membership because I did not want to give the gym my checking account information. The only time it worked was for the initial payment. Since then I have successfully loaded money onto the card so that the gym payment could be processed but when I logged on to look at my account history I see over 50 $1.00 fees for declined payment to the gym. I attempted to contact the customer service which they charge you $1.00 if you want to actually speak to a representative and after the lady asked me for my card number I was disconnected. I log on and of course my card was charged the $1.00 fee when nothing was resolved. I will not continue to call and pay to be disconnected and I will not be adding anymore money to this card. It has a date with the shredder.
