I leave a stamped addressed envelope for anybody who isn't home when I clean. Most are great and send within a few days. However, a few let it roll and pay double every now and then. However, whjat I have started to notice is that more and more are saying 'I was in that day, I don't think I could have missed you' or 'I'm sure I paid that'.
I think I am going to have to start sending reminder texts, anybody know a good way of putting it without seeming overly pushy and how long would you wait before chasing the debt?
