I have two customers who just dont want to seem to pay. its been two months, and ive sent out notices, called them etc.. one lady thinks i charged too much, even though i told her what it would be exactly. they both claim they put the check in the mail the other day, but i am going to get rid of them, because they always pay late and are not good customers. does anybody have a letter you could send me, or i could look at telling them i will drop them? should i send a letter or should i just call? im waiting till i get my money first, thats for sure. this is the first time ive ever had to get rid of a customer for this reason. any ideas?
