treating me like a ***** !!!

I am an honest person selling cds through multiple websites I sell on discogs and have my own website discogs processes payment with invoice and they tell me they wont allow me to pay by payfast this is wrong as discogs is a registered website and they tell me they don't know where I am getting the cds from when they are all I do to make a living as I am a pensioner and survive on selling the cds now they tell me they are disabling my account - this is totally wrong and I want head office and the manager to review this, I think I am been deliberately picked on for some reason,. I own my own house and my dad passes away last year with alzheimers so I keep busy making or trying to make money selling cds - I cant us paypal as I don't have a credit card please sort this out as I need a platform for incoming money from oversea
