Problems with voip

I have been happily using voipcheap for just over a month. I put another 10euros worth of credit on my account and now it is saying that I am not connected and that I have no contacts in my contacts list. It recognises that I am a member and that I have 10 35euros credit - but it won't allow me access to my account. I have used the system and it charges me .05 for a connection fee. Is this their way of getting more money out of me. I've enjoyed being able to talk to friends using this system and now can't. There is no number to phone and no way of contacting voip. Any suggestions would be appreciated.

If there's no email addresses/phone numbers on their website then you should talk to your bank about reversing the credit card charge to them if you're not getting the service you paid for. It's not a quick process, but you'd be most likely to get your money back.
