Breaking a qasam

Q: I have a question. I'm recently divorced as my wife cheated on me with my own brother. Question I have is one day I was caught by my mum saying I love you to a girl and that we will sleep together. This was after my divorce. My mom was very upset and crying a lot so I didn't understand what to do, now she was tense I was tense and crying trying to calm her down. She then ask me to take kasam on her saying I will not look at any other girls fall in love or have sexual intercourse. We are humans and especially I know I will end up breaking the kasam. Is that kasam valid and if I do break it intentionally then what can be done to take the kasam off completely? Also once a kasam is broken is it no longer valid?

Trying to locate the person one owes money

Q: I took my son to a general practitioner about 5 years ago. At the time, I forgot my medical aid card, but the doctor was kind enough to consult my son as I assured him to provide my details the next day. The next day, I contacted the receptionist and provided her my medical aid details. A year after that, I noticed that the fee did not go through my medical aid and contacted the receptionist to inform them. It is now a few years later, and the doctor has moved, and I am unable to get hold of him. He is not listed on any websites as well. How do I discharge this fee?
