Skype.com Suspended my account including my $18 worth of credit. Internet

I opened an account with Skype.com back in 2010.  I purchased $20 worth of credit so that I could make calls to persons that did not have Skype accounts, which costs extra.  Shortly after I opened the Skype account, my credit card number was compromised and unauthorized purchases were being made, resulting in me having to cancel my old credit card number and obtain a new one.

After cancelling my old credit card, Skype.com suspended my account.  Since then, I have not been able to make calls, even to persons who have Skype accounts.  In addition to that, they seized my Skype credit--about $18 worth at that time. 

For the past several years, I have contacted Skype's customer support regarding this matter.  They have not been helpful.  I am never given the opportunity to speak to a real person via phone.  I only get emails from individuals with fake names. They keep asking for my old credit card number, which I no longer have.  When I explain to them why I had to cancel my old credit card number and get a new one, only then will they reactivate my account but shortly after, I get notifications that my account will soon expire.  This has happened 3 or 4 times now so now I am VERY DISSATISFIED!

This is the address of Skype.com--somewhere in France; however, I'm beginning to wonder if it is ficticious, like their customer service reps: Skype Communications S.A.R.L. 23-29 Rives de Clausen, L-2165 Luxembourg.  

In closing, I would like to know if this is happening to other Skype users and if so, how many?
