in summer I visited a doctor, who was by the way the worst I've ever been to, and a month later I received the bill. I paid it immediately and was glad not to see this guy ever again! but ... two months later I received a notification that I should pay this bill. I called the secretary and emailed her the receipt of my payment and everything had been sorted out or that's what I thought until I received a second notification two months later. That time I went there in person and I thought for a second time that everything was all settled.... until today, when the third notification arrived!
Is there any other way to deal with the issue, apart from going back to them and explain etc? Some sort of higher authority to whom I can show the receipt and make those guys stop bugging me?
I am afraid that in the end they will sue me!
