I got a small condo building and they had fallen way back on thier payments. When Dec. 31 got here and I still had not recieved Nov. check I quit cutting and started trying to get someone on the phone. After several failed attempts and me leaving messages with no returned calls a check shows up in the mail paying for Nov. Problem is its Jan. 19th and thier Dec bill is due now but they didn't send that money. In the 3 years I've been in business for myself doing this I suprisingly have never had this situation. How would you handle it? Still not cut until they are current, try to make contact by phone again? Any suggestions are well recieved.
