Dell Safe Online

I don't even know where to start describing the problems I've had with Dell Safe Online backup.  So, I'm posting here in desperation for some help.  First, how do I get help for that specific issue?  Every time I try from the Dell Support Center, I must provide my service tag and the message comes back that my warranty is expired.  I know that.  I just want help with the Dell Safe Online product to which I've subscribed for two years.  My hard drive crashed and I've had very little success in restoring files.  I had not downloaded the Dell Safe Online to my new hard drive because of the low success rate.  But, I decided to not let my account expire so I could keep trying to restore or obtain more files from previous backups.  Went into my account last night to type in the new credit card number and got a message this morning saying there was a problem with that credit card and my account has been deactivated.  I must have made a type, but now I can't access anything since the software is not on my computer.  I can't even get into my account to try to rectify the credit card typo problem.  How can I get some actual assistance with this issue?  I'm willing to renew my account, but am at a brick wall.
