Bad customer service

I have paid my FULL account on Edgars and want to close my account. I still get sms'es and phonecalls informing me that I owe money and they also added some interest as well.

This same thing happened when I had a RCS Game card. They also do not respond to my countless emails with my proof of payment.

This has more to do with RCS than with Edgars. No matter how many calls and emails I do. Their customer service is ridiculous. I will NEVER deal with RCS again.
