Rcs pnp account

Rcs pnp account. I am so frustrated with these people. First when I opened my account I have asked for a debit oder. In the 5months it they debit the money and the they stopped and I have to eft every month. Now they phone me to tell me I am behind on payments wiche I am not behinde. They so *********** because I have sent emails of my proof of payment from my bank to them and still no one gets back to me or can not find the payments. The longer they take I must pay interest and penaltys for them not doing there work. Most terrible place ever and I will not rec them to any one ever.
