Professional Account Services, Inc. called me today, tried to get my bank account information to collect a debt. I knew I owed medical bills but I got a website from them to pay on because I do n't trust phone calls. I pay the bill online but the invoice does n't say anything about what it was for. When I call back to give them the transaction ID number for the payment they said that the debt was for XXXX ambulance rides totaling {$4700.00}, they said {$1000.00} something for XXXX and {$3000.00} something for the other one. I said ok, but when I got home I noticed that those ambulance rides only totaled to {$3300.00}. I called the original debt owner, the ambulance service, and they said that the collection agency charges an additional 40 % for themselves. I go to my bank to try to cancel the payment until I can talk to my lawyer. I could n't stop it because it was pending. I call Professional Account Services, Inc. to ask them if I had to pay the extra XXXX %. They said yes. I told them that when I talked to them earlier they misrepresented what I was paying by saying that I was paying it all to the ambulance service. They said they did n't have to tell me added on fees unless I asked, but I believed there was no reason to ask because they quoted the money going to the ambulance service bill, plus they were talking about taking me to court, plus I trusted the website which also told me nothing. Now I have to wait until Monday or Tuesday to see if I can cancel the payment through them until I can at least get everything in writing or talk to my lawyers, who are also closed until Monday or Tuesday.
